After encountering Angel and Buelsar Elliot, Team Bero, helped by Rak Wraithraiser began fighting with the two until they were told to stop by Vicente who had just arrived. Vicente threatened their aggressors until Hoaqin arrived. The two whiteys chattered until Hoaqin's side began attacking. When Team Bero let their guard down, Buelsar quickly killed Tochi.
Notes and Trivia
Whether he was part of Team Bero at the tournament at Train City is hard to discern, as there was another member present despite him not being introduced. So his first appearance is based on the first clear evidence of him being present, which was when he got transported into the train.
There is not a single clear picture of his face.
In Vol.2 Ch.167 he is never shown, despite being present in the chapter prior and after it, with there even being panels where he could and should have appeared in.
