My Power is Upgrading Everything (Rewrite) - Chapter 25: Oceanic Spirit Beasts

This is a prequel to the anime movie To Aru Majutsu no Kinsho Mokuroku – Endymion no Kiseki.

Just before the completion of the Academy City space elevator “Endymion”, the main characters Kamijou Touma and Index encounter a level 0 girl named Arisa. The Magicians are after Arisa, and they attack Academy City. A female leader named Shattoaura leads a unit from Academy City against the attack. Kamijou and Index learn from Stiyl that Arisa is key to a brewing war between the sides of Magic and Science. When science and magic cross paths, the story begins with Endymion as its stage!

Perhaps the paintings in a museum are subjected to more nonsense than you would hear anywhere else in the world.The language that comes out of an artist’s life is the painting itself. It contains the most ordinary lives that know failure, desire, recoiling in fear, and compromise.Learning is about understanding that language. We miss much of what the paintings speak because there is no way to ask the long-dead painters about the philosophy of their lives.In an alleyway in the residential area of Jongno, there’s a peculiar art gallery. This place enables us to transcend such limitations. By sheer coincidence, I ended up visiting that place and began living an entirely different life.

After an accidental death, in order to continue to live, Gu Bai had to choose to go through various wonderful books to complete tasks.

Every time he became a variety of small cannon fodder inside the story, Gu Bai’s code of conduct when completing task is – by all means, don’t be inferior, don’t be shameless, don’t be upright… hold on to a golden thigh.

… N times after transmigrating

Cannon fodder: (angry contempt) … You’re already so powerful, why are you still shamelessly holding on to a golden thigh to deal with us!?

Gu Bai: (deadpan) That… holding and holding… got used to it…
