Poor Ippo. Sendo, Miyata, and Mashiba are the only friends that are really nice, friendly, and caring than Takamura , Aoki, and Kimura, are the real bullies that gets away their caring onsets to him.
mashiba relationship with ippo is kinda messy considering how much of a menace mashiba was,but aoki and kimura eventually become better except for that one bad role model.
