Even the Immortal Emperor's My Teen Romantic Comedy SNAFU Has Problems

[Slice of life] + [Occasional heat and passion later on] + [No female lead or one female lead] [Anime Crossover]

An Immortal Emperor who lost his emotions as a child because of inner demons unexpectedly arrives in another world for reasons unknown. After signing a contract, he joins a club called the Service Club. As he helps others and his life begins to change, his heart gradually changes as well.

The worlds featured include My Youth Romantic Comedy Is Wrong, as I Expected, Kuroko's Basketball, Baka and Test: Summon the Beasts (tentative), and Detective Conan. More may be added later.

Readers can rest easy: feel free to ship the couples. There will be romance. The author picked the wrong tags by mistake, what a goofball.
