Nanachi/Relationships

Bondrewd
When Nanachi first met Bondrewd, they were fascinated by his vision and decided, like many other children, to follow him to the Ido Front. After the incident with Mitty, they started to feel a mix of fear and hate towards him. After having worked as his assistant in experiments for some time, Nanachi escaped with Mitty.

During the Ido Front incident, with Reg and Riko, Nanachi came to terms with Bondrewd's unusual way to view the world and was ready to leave their trauma behind after Bondrewd told them that his new aspiration is for them to continue beyond the 5th Layer.

Belaf
Nanachi offered themself to Belaf in exchange for the copy of Mitty that he possessed. When the village barrier was destroyed, Belaf set them both free again. Belaf likes Nanachi and the relationship they share with Mitty. Nanachi inherited his will and is able to call upon his instincts.

Faputa
Faputa was shown to feel a sense of victory over Nanachi after being praised for her smell by Riko. During their travels on the 6th Layer, the two grew closer, with Nanachi taking up a sort of teaching role towards Faputa when she has questions about something.

Mitty
Mitty was the only one of the other children to approach Nanachi. Mitty was impressed with Nanachi's artistic skills and knowledge and asked to pair up. Nanachi was reluctant at first, but Mitty insisted and her gentle enthusiasm quickly won Nanachi over. The two grew to have a very close and intimate friendship and were practically inseparable, often even sleeping together to share warmth.

During Bondrewd's experiment, just before the two ascended from the 6th Layer, Mitty's last words were a tearful proclamation that she wished for her soul to accompany Nanachi if she did not survive. Mitty did survive, but was left in a permanently unrecognizable state — transformed forever into a Narehate, and cursed with immortality. After seeing Bondrewd's relentless torture of Mitty's new Narehate form, Nanachi escaped Ido Front with Mitty and vowed to free Mitty's soul from her current physical state.

Their Hideout in the 4th Layer was filled with all sorts of books, homemade plushies, and pillows and blankets, all with the goal of enriching Mitty's life. Nanachi treated her as if she was still a self-aware being, and would talk and read books to her. Despite their peaceful living, Nanachi felt that Mitty was their only reason to be alive, and had planned to take their own life after her death was accomplished. Nanachi felt very strongly about this mindset, going so far as to call Reg cruel when he made them promise not to.

When the day came to free Mitty from her suffering, Nanachi set up a large nest full of pillows and other items they had made for Mitty, so that she could be in comfort even as she was being released. Nanachi said their goodbyes, telling Mitty they would meet again. Only a minute later they recanted this, saying instead they would always be together. When the deed was done, Nanachi fell to their knees and cried intensely.

After the barrier in The Village of Iruburu broke, Nanachi chose to set the reincarnated Mitty free with their own hands. As Nanachi got closer to the barrier, they reminisced about all the new things they learned and with, teary eyes, told Mitty they will definitely meet again. After that, Mitty faded away completely.

Nanachi copes with their loss by telling themself that they will one day meet Mitty again, though they stated that they don't really believe this will happen. Even so, Nanachi holds onto hope with belief that everything returns to the Abyss, and has even been preparing for their fated meeting by learning how to cook good food.

Reg
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
When Riko woke up, after the poison incident, she quickly became friends with Nanachi. They both enjoy each other's company and, unlike Reg, Nanachi allows Riko to touch them; though also not very willingly. Riko named Nanachi the "brain" of the group, due to their vast knowledge and strategic skills.

Srajo
Srajo hosts Riko and her friends, near the entrance to the 7th Layer. She acknowledges the uniqueness of their team, referring to them as "non-pareil" or "without parallel"
