If you get bored at your party Kleekins, look this over:
1. Scorpion? Make him all....pointy and stabby and stuff? It's scareh and it fits because he at one point, scorpion summons (yeah Dakara so inconsistent). But also it kinda invokes the old fable of the scorpion and the frog, how the scorpion can't change its nature and that's kinda what happened to Dakara?
2. Chains - Whatever it is, I was thinking of having chains all over him marked with both Hana-flowers, the Kanji for "Nine" and the Saihoushi symbol. This represents Hana without having to have her head dangling from a string.
Insert more ideas if you got them~
