Calm and rational. Possesses a strong sense of responsibility. Having been raised strictly as the "heir of the Kujoin family" since childhood, he rarely shows emotion. He acts as the coordinator for his younger brothers but is soft on Guest.

Reiji Kujoin Male / 25 years old / 183cm / Fourth Son

Iori Kujoin Male / 19 years old / 178cm / Sixth Son

Bright, cheerful, and active. The type to act before thinking. The most childish among the older brothers, often playing with Guest. An optimistic person who is slightly overprotective.
