Crossover Anime/manga, You Have Absolutely No Sense of Rules, Huh?

A mysterious game called "Ghost Paradise" has changed the world. Following this, an invitation arrives, and Gray joins a chat group called "Mutual Help." The group contains requests for assistance from various worlds; completing them earns a reward. The reward isn't important; the main thing is enjoying helping fellow group members. Yukino Yukinoshita: If I hadn't seen it with my own eyes, I wouldn't believe demons could be blackmailed. Gray acted steadily, unlike a first-time offender. Toyokawa Shoko: In less than ten minutes, she completed an arson attack. Her skill was so practiced, it didn't seem like a first time. Does she really have no prior record? Alicia: The Herrscher occupied an abandoned city as a base, and Gray rushed in and de-urbanized it. Afterwards, the Herrscher came and questioned us about who the Honkai Apostles were. I have mixed feelings. Houraisan Kaguya: She's clearly a beautiful woman with both strength and looks, but she acts like a ruthless bandit. Gray: Who acts like a ruthless bandit? I'm a law-abiding citizen… [Ding! The group name has been changed to "Truly a Mutual Help Group, No Ruthless Bandits in the Group."] Gray: ? P.S.: I already have four completed books, three of which are over a million words long. Updates are guaranteed, so please feel free to add them to your collection and read them. P.S.: This new book is now available, so please, both new and old readers, give me your votes! Thank you so much!
