Rien

Rien, also known by the moniker Fugen Jōtei, was a Tensen-class Sennin who served as the true ruler of Kotaku, the creator of the Tensens, and the leader of Lord Tensen. Throughout her lifetime on Kotaku, Rien had been plotting and experimenting in the ways of Tao in an effort to revive her beloved late husband Jofuku and had aimed to exterminate all life in Japan in order to fulfill this ambition. She is the main antagonist of Hell's Paradise: Jigokuraku. In her youth, Rien had violet eyes and hair, which made up a single large bang hanging from the left side of her face. After living for a millennium, Rien became extremely advanced in age. She had lost her hair and showed traces of twigs and leaves sprouting from her head due to suffering from Arborification. The Tao puppets Rien controlled reflected her youthful appearance from way back and wore the same clothing, which was a white robe, a matching long-sleeved hanfu, a hakama, and black boots. For her departure to Japan, Rien had her main puppet change into Taoist robes that had a decorated pattern on the collars and belt, and wore a crown on her head. Upon her ship being hijacked, Rien loses these robes to fight more comfortably against her enemies, choosing to allow the upper half of her body to be exposed while wearing a beaded necklace and revealed her hidden gold armbands. She also had a ribbon freely float loosely around her. In her Kishikai, Rien gained two additional pairs of arms with their own gold armbands, and three new sets of eyes; a pair underneath her originals and one on her forehead. Her skin became a dark shade and her body received a heart-shaped marking located below her clavicles and two markings resembling flaming wreaths where her abdomen, or tanden, is. Her body also produced a ring with flowers upon the back of her neck. Upon managing to survive having her plant ovule destroyed by Sagiri, a large portion of Rien's body was formed into a bundle of lotus flowers, which included a pair of misshapen wings on her back that seemed to have come from remnants of her extra arms. Rien usually kept herself calm and collected with only her top prioritizes in mind, which was to revive her late husband Jofuku. She was deeply determined in her goal to once again be reunited with Jofuku, having spent countless years going through such horrendous lengths that it ended up completely costing her her humanity. Despite the Banko's many failures that resulted in her having to wait for centuries for it to be revived every so often, Rien continued to endure until she could find some way to see its completion. After encasing his body in gold, Rien made frequent reports in private to Jofuku's gilded body and would also bow in respect, viewing it as her master and a driving force. Although Rien maintained her composure at times, she was not excluded from feelings of emotions, such as irritation and anger, which was usually when she found herself faced with things that are an interference with her plans. During her departure to Japan, Rien wept in front of Jofuku's gilded corpse and embraced it as she expressed her desire to see him again. Later, she displayed happiness at the thought of her plans finally coming close to completion and made preparations for the momentous occasion by laying out items for a married couple. In fact, the only times she remembers being happy was when Jofuku was still by her side. In the past, Rien was noted by the Tensens to have been much kinder and caring. However, following the start of her Arborification, Rien's apathetic personality developed since she found that time was running short for her to complete her research. Since she had acquired transcended powers, Rien had a severe god complex, believing that all mortals were beneath her and that none could come close to even laying a single scratch on her in an act of defiance. She felt nothing for humanity, viewing humans as inferior beings whose only redeeming quality is their Tao that she could use to create Tan, and was more than willing to sacrifice all human life in Japan if it meant that she could have Jofuku back in her life again. This unfeeling attitude also applied to other living things such as the Hōko, having used them for her research against their will and allowing the Tensens to absorb their Tao. Similar to her colleague Zhu Jin, Rien was often vexed when she had to handle confronting troublesome humans who were brave enough to fight against her, finding it absurd that her opponents would have the audacity to think that their low-level capabilities could stand a chance against a Sennin such as herself. Despite her low opinion of humans, Rien did acknowledge the fact that they are not all weak and that there are a rare few who have superior capabilities, such as Gabimaru, Aza Chōbei, and Shija. Despite being perceived as cold-hearted, Rien did possess a sense of camaraderie and compassion. After discovering Mu Dan's corpse, Rien went outside of Hōrai for the purpose of seeking out his killer and expressed her vengeful attitude after encountering Chōbei by asking if he was the one responsible for her subordinate's death. After welcoming Chōbei into Lord Tensen, Rien agreed to the human's request to leave his brother out of the Rite of Consumption ritual after cooperating with Lord Tensen. If anything, despite her neglection to humans, Rien expressed what little compassion she had by wishing Gabimaru pleasant dreams as he Arborified. After receiving words of sympathize from Gabimaru, as a married man, Rien finally learned to accept Jofuku's passing and showed mercy by healing the wounds she inflicted on Gabimaru and Sagiri before allowing herself to move on into the afterlife.
