Joker's Band Game Story

A person who had spent his whole life playing in a band arrived in a world that was like paradise—a world where everyone loved music.
What romantic elements will Ren Amamiya, a band mercenary who works for at least 50 bands, encounter with other bands during the game's release, and how should he act to avoid the occurrence of gravity fields?
What interesting sparks will fly when band members from different bands collide?
In an interview, a man described as "the bassist's lover," "the guy with two instruments," "the king of band mercenaries," "a vixen who is suspected of seducing multiple women," "the strategist who has created over a hundred songs," and "the manipulator behind the band" stated that his titles were largely exaggerated.
However, many people have doubts about this, since some of the titles do indeed match.
"No, at least I have to admit one thing: I am not a fox spirit, but a real person."
Ren Amamiya, who was pinned to the ground by the women and unable to get up, said these words before being dragged into the basement.
