Despite being upset with Kyoka's approach, she is still a soft spot for Supana and can be further exploited to push Supana into despair.

Atropos is colder towards the sisters compared to the bond between Lachesis and Clotho. Atropos threatens Lachesis for even considering defection. For the main cast Renge also lashes out at the treasure boy for sleeping.

It is clear that Minato is a mole here, as he goes against Geryon's plan by leaving Kyoka alone and talking with Lachesis to prevent Supana from becoming a Malgam and Geryon's pawn. Either results will work for him, whenever Minato or Supana wins (the latter happened).

In contrast to Angel Malgam, the benevolent Angelead revives Supana's parents to give him closure.

Though only Takahashi got flak for this, but this is omnipresent though. Not only in KR, but also other series, like if one'd threaten loved ones so that his adversary can fight at full power (due to rage and despair).
