[Crossover] The Most Formidable Tool Character

I'm an emotionless tool, sent wherever I'm needed. Today I'm still a delinquent, watching the strongest man raise a kid; tomorrow I've got to run off and play basketball, mock someone, then get my face slapped; the day after that, I'll be delivering a package to a rundown warehouse and getting mixed up in a deal. And the day after that, I'll have to feed some five-yen god so he doesn't starve to death. Seven days a week, I work eight of them. On the ninth day, the neighboring volleyball club hands me a letter-- I've told you, Mami-chan and I are just friends! - Third-person narration, CP undecided - I'll change the title before posting, but the premise won't change - Hurry, add it to your collection! Theme: Do tool characters even have rights?!
