i have been looking for a series that i have previously watched, but forgot the name of. the information that i know of it is that its a fantasy isekai anime where a guy is playing a game, and gets dropped into another world. in the opening scene, he accidentally stops a robbery by landing on their leader with an office chair. the only other thing that i can think of is that the protagonist either kicks/punches the antagonists testicles out. both of them.
