Gin-san's invited to a Joi Rebels reunion, where he finds Katsura and Sakomoto, fellow survivors of the Joi War era, reminiscing about the past. Sick of seeing them in OPs and EDs all the time, Gin-san tries to leave immediately, but he's shocked by the revelation that the organizer of the reunion wasn't Katsura or Sakomoto, but rather the phantom fifth man, Kurokono Tasuke.
let's plunge into a flashback arc before 
he shows up and see if we recall anything.

que llegue para ver si recordamos algo.
vamos entrar de cabeça no flashback e ver 
se lembramos de algo antes que ele apareça.
