Peebo also tells him that what he did was right instead of being guilt over the loss of Kenta's father as Shingo became frustrated after he fights the disguised mechaclones or not to which Hikaru convinces Ryuta to tell him. Ryuta also tells him that they were fighting for their life and what he would do to which Shingo becomes upset by this telling him to protect it not to destroy it which he blames himself for killing Kenta's father.
