Summary[]
The whole KBG crew charter Ippo's fishing boat to catch some fish and Yagi decides to make a bet of who can catch the most. Takamura and Kamogawa can't catch anything and eventually Takamura gets annoyed and starts rocking the boat trying to catch a huge fish...only to reel in Aoki who he knocked off the ship accidentally. Later, Kamogawa announces to everyone Takamura's world middleweight title match along with Miyata's OPBF featherweight title match. Takamura and Miyata go to a training camp together where Miyata realises how weak he's become from just training by himself with nobody to look up to.
