Rokuko/Relationships

Keima
She summoned him as a gatcha prize. She learns how to operate the dungeon from him. Even though he is as lazy as one can be, Rokuko has fallen in love with him through the novels.

Haku
She is the older sister of Rokuko. She taught her when she was born. Rokuko can always rely on her.

Niku
As she is a slave, Rokuko believes she is an item that belongs to Keima. That's the reason why she can enter the master room in the core. She is strong, so Rokuko leaves Keima in her hands most of the time.

Ichika
As Ichika is an "experienced" woman, she considers her as her teacher in "that" field.

Soto
The daughter of Keima and Rokuko. She was born when Keima and Rokuko mixed their mana together in the spare dungeon core to try and enter its master room. When trying to think of a name, Keima suggested to name the new dungeon core temporarily (for now) as Soto. Rokuko liked the other world name and called her Karini Soto aka "temporarily (for now) Soto".
