Reg/Relationships

Faputa
Reg met Faputa and Gaburoon shorty after the latter had been damaged by a Turbinid-Dragon. Faputa was at first wary of him, but as they spent time together they grew closer to each other and Reg gifted Faputa the googles he wore on his helmet at the time as a sign of friendship.

Kiyui
During Reg's time in the Belchero Orphanage, he and Kiyui were both Bell Whistle Delvers. They frequently spent time together when Nat and the others are out cave raiding. They appear to have bonded, as Reg made sure to visit Kiyui and say goodbye to him before leaving with Riko for the Abyss.

Marulk
Riko and Reg are the first people around Marulk's age coming to the Seeker Camp. Marulk quickly bonded with them and they became friends. During their stay in the Seeker Camp he explained a few things to them. When Riko and Reg advance to the next layer Marulk, together with the other Subterranean Bandits, sees them off.

Nanachi
Nanachi first encounters Reg while he is trying and failing to save Riko's life after their encounter with the Orb Piercer. At first, both Reg and Nanachi tend to be reluctant to show their feelings to each other, but over time they have become close friends and trusted comrades on their journey.

Nanachi doesn't like being touched by him, saying the way he does it is "too lewd". Reg often comments that Nanachi is fluffy.

Riko
Reg supposedly saved Riko from a Crimson Splitjaw in the Abyss's 1st layer. Riko brought him back to Belchero Orphanage while he was unconscious and, with the help of Nat and Shiggy, woke him up. At first, Riko was fascinated by Reg and saw him more as a Relic and advanced machine than a person. However, this did not stop them from quickly becoming close friends and learning to depend on one another's skills in the Abyss. Riko was also the one that gave Reg his name, and he treasures it very much because of that. Over the course of their adventures, Reg's actions and thoughts have shown that he cares deeply about Riko and feels very protective of her.
