@NotSomeone@ICooKI Story wise it wouldn't make to much sense for Ippo to return to the ring thou since as far as he knows he's punch drunk. And that fact has been hammered down time and time again since his last fight. Honestly i'll imagine the series will end with Ippo just taking over the family business rather than anything else at this rate. Or take over for kamogawa as a coach.
He hasn't been confirmed as Punch Drunk, Ippo is afraid to enter into the "World of Monsters" which is more implied than him being punch drunk. He basically has anxiety issues.
