[Crossover] Qi Shuikong Rejects Overtime

Tobirama is at his wit's end. After finally letting go of everything and dying, he somehow ends up transformed from [Senju Tobirama] into [Saiki Tobirama]. Tobirama: ...Is it really that hard to get some sleep? He spends his days working on cutting-edge technology with his big brother Kusuo, feeding his little brother Kusuo coffee pudding, taking in the yokai Onikiri, occasionally looking after two University of Tokyo students, Irie and Byakuran, watching the inhuman dribbling on the sports channel, and listening to the high rate of deaths in Beika Town. Life is carefree and easy. Then one day, Alaya, the one who tossed him into this world, whacks Tobirama awake: "Tobirama! Get over here and repair the Singularities!" Tobirama: What??? From then on, his Flying Thunder God Technique starts malfunctioning... Planned worlds: I. The Flying Thunder God Technique Is Always Unstable 1. A hands-on guide to babysitting the King of Heroes in Uruk 2. The former strongest Port Mafia executive helps the boss polish diamonds 3. My uncle somehow became a slime and built a nation II.

Content warning: Multiple one-sided romantic interests, endgame pairing is 1v1 Gilgamesh -> Tobirama, Madara -> Tobirama, (secondary pairing: Soukoku, proceed with caution if that's not your thing) Recommendation: Upcoming Crossover, The Port Mafia's Songstress, Miss Chuuya In the third year after Osamu Dazai's defection, Nakahara Chuuya faces a deadly crisis: his influence can't keep pace with Arahabaki's growing power. He plans to die in battle on a mission, but ends up being kicked by Boss Mori Ougai into a new field instead: "Go genderbent and become a Yokohama idol, Chuuya!" Nakahara Chuuya: ...Boss, do you remember that we're the mafia??? From then on, the Japanese pop scene gains an explosively cool Yokohama songstress, Aohara Moriya. With fluffy orange hair, a slightly husky smoky voice, and a defiant, challenging gaze, she leaves fans everywhere unable to resist, all shouting, "Miss! Step on me!" #Even if Master Ranpo gets lost, he'll still make it to the concert# #Why has the future tenth boss of a certain mafia become obsessed with idol fandom?# #In the world of mysteries, the culprit gets kicked into the air# #The yokai offer up their faith, sustaining the god Arahabaki# It's one thing for a Port Mafia executive to moonlight as a songstress, but our hard-working Port Mafia member Nakahara Chuuya keeps losing control of Arahabaki's power and tearing holes in the barriers between worlds. To get back to their original world, he is forced to perform and work with a certain mackerel in another world. Chuuya: Even if I die! Even if I jump from here! I absolutely will not let that mackerel uncover my secret identity! Dazai: The little shrimp doesn't seem to realize his secret identity is already exposed. Then I guess it won't hurt to go a little further~ Planned worlds: 1. Even the pirate navy are fans (One Piece) 2. Who says a little shrimp of a songstress can't beat the stuffing out of aliens? (Crossover with American comics) 3. To be decided Setting: 1. On the surface, Chuuya is the safety mechanism for [Arahabaki]. In reality, he is constantly adapting to [Arahabaki]'s power and becoming a true god. 2. Mori Ougai and Kouyou know Chuuya's true identity. 3. CP: Soukoku Theme: Responsibility
