They release an album and start touring

"Ok so you ladies go to bed and I'll focus on mixing the album for some time here. I think we set a release date for later this month." Tomoki tells the girls. After about a week of final touches of getting the mixes right and getting pleasured by his harem. He finishes his work and Mirai contacts an artist for an album cover.

"Hey Kaede, we need you to make an album cover for a band I'm helping manage." Mirai tells the artist, named Kaede.

"You're in a band now? This seems a bit sudden. Well do you guys have an idea of what you want for the cover?" Kaede asks.

"I think the band leader said he wanted something spacy or something since apparently that's common with this music genre."

"Oh ok, I'll try. And when do you need it by?"

"The day before its scheduled release." She tells Kaede the scheduled release.

"Oh ok, got it." Kaede hangs up.

Some more weeks pass and the album cover is sent and approved by Tomoki and he attaches the music to it and posts on Bandcamp. He says to Mirai he wants to potentially get physical releases of this album later but decides this is enough for now.

Some tours have been planned and they start out local and somehow ascend into being regional headliners. Fitting into Tomoki's perverted nature, he tries to find a way to rig the stage to rip off the women's clothes at every show they were at. He's technically the star of the show, being the lead singer and all, but he decided to give his audience some eye candy of a bunch of busty ninja babes suddenly being naked. It helps that 2/3rds of the girls on stage were already wearing skimpy outfits to begin with. Apparently this was what made his band really popular since well, sex sells. Though his ticket prices were relatively normal, around 4000 yen, the audience tossed money everywhere to the stage like they're watching a strip show. Well, they technically were, but the stripping was near instantaneous as opposed to slow and teasing. The rest of the ladies he's acquired were a large group of, well, groupies which he occasionally had sex with on their way to all the venues. The large amounts of tips afterward and his cramped house situation gave Tomoki an idea.....
