A crossover anime/manga story, set in everyday Tokyo, but within a loop of a game.

Utsunomiya Asagiri transmigrates to a world where various anime and manga have merged, and grows into a handsome Tokyo guy—a standard protagonist template. Both his parents are deceased, and he is the only person listed on his household registration.
Just when he thought he could live a peaceful daily life, he entered a reincarnation game similar to the God's Space.
Moreover, the player who appeared in the same ward was a freshman who entered Shuchiin in the same year as him, named Yuuki Asuna.
Bad news: The reincarnation game is extremely dangerous; a slight mistake can lead to death.
Good news: This game has very generous rewards, and Asagiri really enjoys playing it.
A born reincarnation game player, the Demon King of Shuchiin, leading the strongest conquest team, the unruly and talented Persona user codenamed Leader makes his grand entrance!
[Initial teammate setup: Asuna Yuuki (from Sword Art Online), Kotoko Iwanaga (from In/Spectre), Megumi Kato (from Saekano: How to Raise a Boring Girlfriend)]
[Like the previous book, it's a true harem where there's no factional strife and everyone's just playing the stock market; the male protagonist is abstract and often very direct.]
