I feel like we either are missing an entire arc before this, one focusing on Ishida actually working out his inner demons, the same way as he had that whole killer mentality put into him
Or an arc after this one in which instead of retiring he does boxing for himself rather than for the pressure of his family
Feels incomplete, but well, we got a happy ending, and they had a propper boxing match, which is what i actually wanted their first ring match to be
