Yaone - Yaone and Dokugakuji have a very supportive relationship. Since the two of them had both been taken in by Kougaiji they both have devoted themselves to him. When Kougaiji is taken by Dr. Ni because he has sustained substantial injuries, the relationship between the two of them deepens a bit. Both feeling guilty because they could protect neither Kougaiji nor Lirin, they lick each others wounds and strength each other, determined to save Kougaiji and eventually Lirin.
