Hokuto, Kairi, and GarudaMan, they really want to milk these three and not show anyone else. Actually, do they even have any other character or are they just working solely on these until they're completely 100% fully perfect ? Because that would explain why they never did anything until this.
If I struggled to the end of my determination, to the end of my way of life with my followers, if the result is ruin, then this ruin is inevitable. Grieve. Shed tears. But you cannot regret.
