In the anime, people are in everyday Tokyo, but they are playing the reincarnation game

Utsunomiya Asagiri, traveled through the world of souvenir manga and grew up to be a handsome man in Tokyo, a standard protagonist template. Both his parents died, and he was the only one registered in the household registration book.
Just when he thought he could live a peaceful daily life, he entered a reincarnation game similar to the main god space.
And 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 and you can die if you are not careful.
Good news: The rewards for this game are very generous and Asagiri enjoys playing it.
A natural born reincarnation game player, the Demon King of Shuchiin, leads the strongest strategy team, and the unruly personality mask user codenamed Leader makes his grand appearance!
[Initial teammates: Yuuki Asuna (from Sword Art Online), Iwanaga Kotoko (from Fictional Reasoning), Kato Megumi (from Passerby Heroine)]
[Same as the previous book, a real harem without party disputes and stock speculation, an abstract and often straightforward male protagonist]
