Overview
As the story begins, Kitazaki loses a battle to Faiz. He can't believe he lost. Takumi still doesn't quite believe in himself and gives the belt back to Mari. He then goes to the Lucky Clover bar to deliver a challenge. Later he meets up with Aki who tells him more about what happened after the reunion. He then sucker punches Takumi and takes his place in the fight with Lucky Clover. He calls Mari and asks her to save Takumi. As Aki is fighting Lucky Clover, Masato shows up to fight him. Shuji finally decides to enter the battle with the Orphenochs as Delta and shows up as Masato starts to battle the rest of Lucky Clover. Aki dies as a result of his battle with Masato. As the story comes to a close, Takumi seems to have made the decision to fight along side Masato and Shuji as a human-Faiz.
