Help! I changed the gender of the male protagonist in the yandere game

For exorcists, whether it's martial arts or sorcery, mastering them requires a long time of dedicated study, focus, and commitment to integrate the skills of predecessors and reach the pinnacle.

Theoretically, it's impossible for someone in this world to learn another person's moves on the spot after only seeing them once or twice.

However, this is an inexplicable "phenomenon" happening with Baikai right now. He hasn't had any real contact with the Gun Saint, hasn't received any guidance from him, and has only fought him briefly in a dream.

To be able to learn an opponent's moves with just a fleeting glance during a fight is, to anyone, a complete fantasy.

Baikai doesn't realize how bizarre all of this is. All he's thinking about is how to defeat this powerful demon.

"If it were a fully powered Greater Demon... there's really no way we could win, even if we all worked together."

But, if this demon had just broken free from a 150-year-old seal, was weakened to the extreme, severely injured, and unable to use even its past familiar demonic spells and curses, with fatal flaws, then it might not be impossible—

'The beetle demon, Bee-Horn, has two fatal flaws.'

First, there's a damaged section of its carapace on the back of its neck. Aiming for this weak point would be enough to kill the demon.

Second, the beetle demon's visual ability was "slain" by a powerful figure in the past. It was a strike that could sever the senses, destroying its ability to "see" things—although it has glowing, ruby-like eyes, it can't see at all.

Demons can use their demonic power to detect surrounding spiritual energy, like radar, to observe their surroundings. For this demon, even without sight, the impact isn't too significant.

The problem is that the power of that initial slaying strike was too strong. The range of its spiritual energy detection doesn't exceed a radius of ten meters, and its sensitivity is greatly reduced.

It can barely detect movements outside of that range, and its perception decreases in complex environments.

Baikai puts all his effort into this one shot, pouring all his spiritual power into it. The "explosion" he creates on the ground can't compare to the power of the Gun Saint's move in the dream.

The "Dusting" gun technique itself simply uses the blast to create a smoke screen with the dust on the ground, using falling gravel to hinder the enemy's movements.

The Gun Saint could use this move to create a sandstorm-like attack, with large amounts of shattered stones and gravel blasting out like bullet shrapnel, causing even greater damage.

However, his move also created a concentrated "rain of gravel" within a certain area.

For the beetle demon Bee-Horn, this was like a heavy rainstorm, severely disrupting its senses.

"Success."

Baikai throws away the gun. After successfully executing the "Dusting" technique, he draws his ninja blade and dashes forward.

He doesn't have much spiritual power left. Just creating the explosion consumed a third of it. He pours the remaining spiritual power into his thigh muscles, fully enhancing his leg strength.

Bang!

Baikai pushes off the ground, as if compressed air is spraying from beneath his feet, rushing forward like lightning. In an instant, he plunges into the rain of sand and dust.

The beetle demon Bee-Horn's awareness is a beat too slow, or rather, in the face of the sudden "torrential rain" disrupting its detection, it doesn't have time to react in time, until Baikai rushes into its blind spot.

Then, running in a straight line towards the front of the beetle demon, the demon realizes the enemy's intention when he's almost within reach.

'Taking advantage of the chaos to disrupt my senses and launch a sneak attack, this is not the way of the warrior, this is a despicable tactic!'

The beetle demon is enraged.

However, it also knows that the enemy has timed it perfectly.

The spear is broken.

The hand holding the sword is severed.

Its only weapons are the close-combat axe and the defensive shield.

Although the shield can absorb and reflect spells, the flames it absorbed earlier have all been released.

'An ambush timed to take advantage of my condition?'

However, it still adopts the most appropriate and conservative tactic on the battlefield, using the shield to block its front and defend against the falling gravel. At the same time, it puts all its strength into the handle of the axe, ready to launch an attack at any moment.

This is the beetle demon's strategy: to deflect and scatter the opponent's attacks with the large shield in its left hand, and then take the opportunity to attack with the axe in its right hand.

As long as the enemy's attack comes, no matter from which angle in front, it can react in time.

However, at that moment, Baikai makes another move. He throws a stone forward.

"Thud," the shield makes a dull sound.

"What?"

Out of caution, the beetle demon holds the shield horizontally and vertically to defend, and in that instant, Baikai jumps into the air.

"Courting death."

It swings the axe in a sweeping motion, predicting the opponent's trajectory in the air. The axe blade can cleave Baikai's body in mid-air.

However, the axe misses, striking a mass of air.

Wrong!

The enemy is gone—

In an instant, it realizes its mistake, but it's too late.

"Thanks."

Baikai disappears in the air, teleporting onto the shield. He uses the "Shrinking Earth Amulet", ignoring time and space to jump onto the large shield. Taking this opportunity, he steps on the shield and leaps into the air, performing a second "Shrinking Earth."

This time, he instantly teleports behind the beetle demon's neck, aiming for the visibly cracked carapace, and forcefully stabs the blade tip into it.

The beetle demon lets out a miserable scream. This is a fatal blow.

"Incredible... Baikai, this kid...!"

Old Man Matsudaira stands still, holding his naginata, muttering to himself in astonishment.

The branch family head, Karaiya Ba, also opens his mouth slightly.

At the same time, Nightlight, who is dodging the flames and retreating to the edge of the courtyard, stares intently at Baikai's figure.

"Success."

Without the slightest carelessness, Baikai, not even bothering with the ninja blade, uses all his strength to perform a third Shrinking Earth, using the power of teleportation to jump behind the beetle demon.

The great beetle demon, pierced through its vital point by the ninja blade, roars and swings its axe backward. Baikai quickly dodges, but he doesn't have enough spiritual power to use Shrinking Earth again, and his stamina is running out, so he can only dodge clumsily.

He dodges very barely, almost getting hit by the beetle demon's death throes.

"Vermin! Seeking death, ah ah ah ah ah ah!"

The beetle demon roars, its voice revealing its near-death state.

Swoosh!

The axe blade slashes through the air.

Baikai doesn't have time to dodge.

"Clang," the large axe collides with the raised double swords. In a burst of metallic sound and sparks, Nightlight raises her swords, using spiritual power to resist the large axe.

The beetle demon possesses natural brute strength, but the girl's arm strength, enhanced by spiritual power, is actually on par with it.

"Everyone, attack together!!!"

She shouts, and Old Man Matsudaira and Karaiya Ba immediately respond to her call, launching a joint attack.

Old Man Matsudaira roars, and the naginata slashes through the air. Karaiya Ba throws out several talismans, which transform into ice blades and golden arrows. The firebird Bifang also launches an attack, bypassing the shield and actively crashing into the beetle demon's face.

This is a desperate strike. The firebird turns into a flash of light and explodes. The intense heat causes the beetle demon's horns to evaporate, its head to shatter, and the carapace on its right shoulder to char, shatter, and evaporate.

Scattered sparks shoot out, and where the sparks land on the ground, the earth is exposed and boils and bubbles due to the high heat.

Nightlight waves the Mizuchi Sword in her hand, and the beetle demon's right leg is severed. It falls backward in pain, spraying a large amount of blood from the severed section. The severed right leg rolls in the sand and dust.

"I can't fall here yet, ah ah ah ah ah ah!"

It supports itself with the shield, but its left knee is forced to the ground due to weakness, slamming the severed stump of its leg into the ground to stabilize itself.

"Now!"

Tsukiyomi Nightlight commands in a steady voice.

"Keep attacking until it's killed, until it can't move."

The naginata slashes down in a grand sweeping motion, severing the arm holding the shield; ice blades and golden arrows shoot in densely, and the beetle demon screams again, but still fights back desperately. Finally, its axe is shattered by the girl's spiritually charged strike.

The exorcists, with their tacit cooperation, combine to unleash their battle power. Even the Greater Demon, who in the past could sweep across human armies on the battlefield, is beaten into collapse.

Finally, it crashes to the ground.

Its whole body is bleeding, and the ground is covered in blood. The beetle demon's life is declared over.

'It's a pity... Although this guy is a demon, he's an interesting character in the story. His wish is just to die like a warrior on the battlefield. In the original story arc, he's defeated by the protagonist in a fair fight, and he fulfills his wish before he dies...'

Baikai sighs in his heart.

However, without aiming for the opponent's weak points, this battle against the beetle demon Bee-Horn would definitely result in heavy casualties.

Perhaps the protagonist Nightlight could survive by powering up.

Himself, Ayaka, Old Man Matsudaira, and Karaiya Ba would most likely die, the monks of Gango-ji Temple would die, and his subordinates would also die.

"So, you must die here."

Baikai looks at the beetle demon's gruesome remains and shakes his head.

"Is... is it over?"

After defeating the beetle demon, Nightlight also breathes a sigh of relief.

"Baikai-sama, are you alright?"

She asks Baikai in a concerned tone.

"I'm fine, but I've used up all my spiritual power, and I can't hold on anymore."

Baikai's thin lips make an extremely tired sound.

"I probably can't move now..."

Using the Gun Saint's gun techniques and activating the effects of the Shrinking Earth Amulet has brought a burden he hadn't imagined before.

He was in a desperate state before and hadn't noticed his physical condition. Now that he's come to his senses, he realizes that his stamina is almost exhausted, his muscles are aching terribly, and his whole body feels as heavy as lead.

"It's alright, I'll support you."

Nightlight gives a sweet smile, supporting his swaying body.

Baikai is stunned for a moment. That's clearly a woman's smile. Where is there any trace of the male protagonist?

"Brother."

Ayaka rushes over from behind in a panic. She was arranged by Old Man Matsudaira to take refuge in the back, and now she sees Nightlight and Baikai clinging together, so she hurries over.

At that moment—

"Ooooooooh!"

The beetle demon's remains, which should have died, the beetle demon who should have fallen in its own sea of blood, forcibly props itself up and rushes towards Ayaka.

Not good!

This is a scene that exceeds the expectations of everyone present.

However, in the next instant, a silver moon wheel cuts through the void.

The beetle demon's last attack freezes midway.

Then, its body splits into pieces, and blood rain and internal organs spill from the cross-section.

"...Are you so disheveled from dealing with just one enemy?"

A clear voice slowly rings out.

The light of the moon wheel ends, and without anyone noticing, a black-clothed man dressed in a monk's robe appears there.

His right hand holds a long sword, and with a casual wave, he scatters the blood and fat clinging to the blade on the ground, forming a blood-red arc-shaped mark.

"Nightlight, I thought you could become a little more mature after spending some time at the Black Himeyama family... In the end, you're still like this."

"B-Big brother?!"

Ayaka kneels on the ground in shock. When she raises her head, she murmurs, "Is that you?"

"I-Ikki-aniki."

Nightlight also freezes in place, her lips even stiffer, her eyes staring blankly at the man in front of her.

"You've really disappointed me, Tsukiyomi Nightlight."

Kukutsu Ikki shakes his head, spitting out harsh words while reinserting the sword into its scabbard.

This...

Baikai is also extremely surprised.

'Kukutsu Ikki... How did my brother-in-law come here?'
