I can travel through countless worlds at the same time

(Doppelganger style) + (Comprehensive manga style) + (Multiple heroines)
Bai Ye traveled through time, without a system and without an old grandfather.
Fortunately, he traveled through more than one world, but countless worlds at the same time.
Demon Slayer Bai Ye: "Boss, you scumbag? Come out and get some sun. It's not good for your health if you don't get in touch with the sun for a long time."
Heroic Spirit Bai Ye: "When we come, it's time for the stars of humanity to shine."
Greymon Bai Ye: "Puppymon, don't become like that in the future (pointing to the picture of Holydramon)".
Passerby Bai Ye: "6"
Pokemon world, God Slayer world, Ultraman world, No Game No Life world...
All Bai Ye: "I have achieved what I have today by my own efforts."
