I am beginning to think Kamito may be responsible for all of our heroine's woes

Spoiler for spoiler:

Renselt's sister was frozen in a ice coffin for annoying the Ice Ele Queen-3 Years ago. Possible due to Kamito's impromptu assassination attempt?

Claire's sister went crazy at the same time, possible due to Kamito's actions as well. Especially now she is pretending to be Ash Renbell and gunning for Kamito.

Finna lost her rights as princess due to Claire's sister.

Ellis's sister went berserk directly due to Ash Renbell.

So apparently, all 4 girls are in love with the guy who screwed them over, if indirectly.
