makes you wonder if the mecha that red uses for maximum kizuna kaizer is his friend's actual mecha, or just one of those spare part mecha that sentais would get along the way, in this case probably by bonding with them.
@Yarramie probs becuz this is a doujin/fanart only, not an actual series.
WOULD ACTUALLY WATCH IT tho if it were an anime, but first thing first, either a manga or a LN adaptation first, like that 50 y/o man who became a otoge rival.
