Belaf

Belafu is one of the Three Sages of Ilblu. As human he used to be one of the key members of the Ganja Suicide Corps and is now one of Ilblu's most important residents.

Appearance
Belafu has a long, centipede-like body, while his head is more reminiscent of a flower. He has almost no facial features except for what is at first glance two empty eye sockets. These "eye sockets" are actually more akin to mouths; a proboscis-like tube protrudes from each hole to take in food. His voice also comes from these openings.

As a human, Belafu was thin and tall. He had wild hair and a large scar across the left side of his face. His eyes were beautiful and light colored and he always had an intense expression on his face.

Personality
Belafu's personality is a stark contrast to Wazukyan's laid back nature. Belafu is willing go through any means possible to get what he wants, even if it means destroying his own body, but is also considerate towards others; as seen when he gave Riko the choice what to trade for getting Nanachi back.

As a human, Belafu was a much warmer person. While still intense and intimidating, he was very insightful to others thoughts and feelings and helped raise Vueko's confidence during their travels. He was also just as intelligent; he served as the main translator between the Abyss's island natives and the Ganja crew.

Ganja Arc
Belafu was once a human, part of the Ganja Suicide Corps who aimed to find the Golden City at the bottom of the Abyss. Belafu was one of Ganja's Sages, and the main translator for the Abyss's native people. After Ganja had created a Camp on the 6th layer and started to suffer symptoms of an unknown body-hardening disease it was Belafu who discovered the source the disease. He also fell ill from it, due to them having no alternative source of water, but was later healed by "medicine" given to him by Wazukyan. It's revealed the food Wazukyan had fed Vueko, Belafu and other Ganja members, who gotten infected by the "Mockwater", is broth made from Irumyuui’s children and to his surprise it not only gave nurishment to the infected, but also alleviated the symptoms of their infection.

Upon this reveal, Belafu was shocked that he consumed Irumyuui’s children and suffered a mental breakdown, blaming himself heavily for having willingly eaten the broth while he was under the effects of the Mockwater. He’s later seen being fed by Vueko due to having starved himself to the point of being unable to move and yet still pleaded for her to stop feeding him broth made from Irumyuui’s children.

When Irumyuui, after her last transformation, started to consume predators of the 6th layer Belafu, still plagued by guilt pleaded to her to consume him aswell to make up for having eaten her children. A giant hole opened up in Irumyuui, allowing Belafu to walk right inside her. As Belafu’s flesh was consumed he was simultaneously reconstructed and transformed into a Narehate. The other Ganja members, struck by the "beauty" of Belafu’s new form, concluded that they would be forgiven for eating Irumyuui’s children if they offer themselves up to her in the same way and Wazukyan proclaimed that this is the home they had been looking for.

Early Life as Narehate
During one of Bondrewd's reportedly many visits to the village, he brought Mitty with him. Belafu was able to sense Mitty's true immortality, and decided he had to have her for his own. Bondrewd refused to sell her to Belafu no matter what was offered.

So instead, Belafu sacrificed all 724 of his arms and legs, half of his body, part of his sensory organs, and "reduced and used their value" in order for Mitty to be reborn in the village. Belafu uses Mitty as his main source of food, since no matter how much he takes from her, she regenerates due to being immortal.

Ilblu Arc
After Nanachi hears from Majikajya, during a conversation about value, that Belafu is in possession of of the supposed-to-be-dead Mitty they ask Majikajya to take them to Belafu. Uppon visiting the sage's house Nanachi is moved to tears out of happiness to be reunited with Mitty, but is shocked moments later as they watch how Belafu extends his feelers to drink from Mitty. Because Nanachi wants to save Mitty from more torment they offer themself up to Belafu in exchange for Mitty.

Later on, Riko visits the sage since she has been informed to find Nanachi with him. Riko finds Nanachi and Mitty with Belafu, and he tells her that the Mitty he has is a clone created from the original brought by Bondrewd to the village whom he wanted to use as a nutrition source—because he couldn't afford to buy Mitty directly from him, he sacrificed half of his body to have the village replicate her. He also tells her about how Nanachi offered themself up to him and that he is willing to sell her back to Riko in exchange for something of similar value.

He suggests to her to trade both her eyes, both her legs or her complete digestive system to him. Before Riko can make a deal with him Majikajya closes up her mouth, tells her not to be hasty and Riko gives up for the moment.

High Regeneration
In order to obtain Mitty, Belafu sacrificed most of his body. Most of it seemed to have been regenerated or healed over time.

Nutrition Absorbation
Due to his bodily changes as Narehate, Belafu is able to absorb nutritions from other living beings by inserting his proboscis-like tubes into one of their orifices.
