I Live My Life as a Big Brother in a Variety Show

[The female protagonist is invincible + the female-to-male/female-disguised-as-a-man plot is available + the world view of the comprehensive comic + setting adjustments are available] Time travel is the saddest thing in the world, and traveling to the second dimension of neon is even more tragic in sadness. So what if you travel to a world of neon two-dimensional hodgepodge? Xu Yunhua (Purgatory Momojuro/Akiyama Jiro/...): Destroy this world! The comprehensive comic covers: Demon Slayer, Curse, K, Bungou Stray Dogs, Tutor, and even some HPs will be involved. Note: The female protagonist will have a gender change, and there will also be a plot where she disguises herself as a man. However, since the story is a flashback, the personal pronoun is "he". The characters are unclear and the route is clear (the career team can't accept that the protagonist can compete with or even overwhelm the forces of the original work if they directly work alone, so they can quit. This fan is just following the path of "monstrous power" + "struggle for power and profit", and he really can't talk about love) There are also a large number of original characters appearing (in order to round out the distorted historical development in these world views... Everyone can just treat it as an imaginary world and make a comprehensive comic)
