I Transmigrated to the Inner World and Created a Service Club, and I Want to Win at Life

I transmigrated, and thought I was in the lighthearted romantic comedy everyone loves. I never expected to end up in a super-dangerous Tokyo that mixed Mieruko-chan, Tokyo Ghoul, Jujutsu Kaisen, and Nura: Rise of the Yokai Clan! Luckily, killing monsters lets him gain spiritual power. That works too. He can fight his way through countless hardships and reach the summit, making for a story worth telling for generations. But a second System notification suddenly rang in his mind and shattered all his plans. Under the System's missions, he starts a service club, builds up his team, and turns ordinary people into psychics. Here you'll find Rikka Takanashi, known as the wielder of the Evil Eye! The lonely hero Bocchi, who excels at using strange sonic attacks! Yukino Yukinoshita, a catgirl with incredible athletic ability! Kotori Itsuka, who transforms into the spirit demon of flame, can burn everything to ash, and keeps coming back like an immortal phoenix! And Yukino, the Deep Winter, who can plunge an area into absolute zero and even freeze time for a short while.

The main plot is fighting the supernatural; the side plot is conquering the female characters of the inner and outer worlds, turning them into subordinates (wives) and reliable companions in the fight against the supernatural.]
