[Honkai Impact 3rd] [Blue Archive] The following is told from the protagonist's perspective:

I transmigrated to Blue Star. My parents were both dead, and they left me 2.1 billion. All I wanted was to lie flat as a rich second-generation kid, but from the start I gained all of Sukuna's, Satoru Gojo's, and Liu Buhu's abilities, along with the Grand Zi-O Ridewatch and the Dark Ring. When aliens suddenly appeared at a convention and everyone fled, I took off my sunglasses and said, “Domain Expansion: Unlimited Void.” When Leviathan descended on the East China Sea and the military was helpless, I enchanted Malevolent Shrine with Gatanothor's power and chopped it into mince. Later, I transformed into Tiga and livestreamed across every platform as I headed to that small country to the east. I beat more than fifty monsters to death in one go, then blew up a star in front of billions of people. “It was just a deterrent,” I said. The Myriad Worlds chat group pulled me in. The Dragon Clan, Rule-Bound Horror Stories, Kivotos, Genshin Impact, Honkai: Star Rail, Honkai Impact 3rd... The Dendro Archon, the Hydro Archon, the Electro Archon, Hoshino, Shiroko, Hina, Elysia, March 7th... They're all mine. Dozens of girls moved into my Sheshan estate. They say I'm the light. I say I'm just a passerby.
