However, when the important friends (Nami and the Oni Brothers) explains that their friends are not murderers, they are now become no longer be aggressive persons.
    • Ritual [Fun]: Yuya Sakaki
    • Fusion [Faith]:  Zuzu Boyle is only member that Samuel Nakaoka the Second used her body as his second body. Zuzu's personality was mixed with Samuel Nakaoka's personality into a new personality as Zuzu-Samuel.
