Kagura

Past Timeline
Kagura was the daughter of a shaman and was able to have a normal childhood unlike her sister, the successor. However this changed when Kagura was appointed as the shaman successor since she had foresight unlike her sister. Eventually Kagura becomes a shaman and is given the Eight Serpent Sword which is a family heirloom. Later a curse which was sealed within the sword broke and Kagura's mother sacrificed her life to seal the curse.

After the curse of destruction spread, the seal of the curse broke again. Kagura tried to sacrifice herself to seal Orochi's (demon in the sword) curse but was consumed with the power of destruction instead. She then went on a journey to keep the the curse from releasing.

Season 2
Kagura traveled around looking for ways to permanently seal the curse. Kagura went to Moonlit Isle and Lina noticed the suspicious energy coming from her which is when her demonic Orochi side woke up. With the help of Jin, Lina was able to try to cure Kagura but the curse was too strong. Daisy was also hurt in the process and affected by Kagura's curse (which relates to Ace's awakening scenario).



After multiple possessions and awakenings of Oorchi, Ace is forced to attack Kagura and is able to release her from the curse of Orochi. A rumor later spreads that Kagura is Ace's fiancee but Daisy confirms is nothing but a false rumor. Due to orochi, Moonlit Isle was soon completely covered by evil spirits and souls.

It seems that Oorchi's curse is said to work in a similar way to that of the power of the devil that Shane and Kris have. After the whole Moonlit Isle is surrounded by spirits, Daisy becomes engulfed by the curse and is later taken to the temple of Lina to recover. Kagura continues to search for a way to finally end her curse and seal it forever.

She also appeared in a valentine's day cutscene in the Japanese version where she shares some chocolates with Ace.

Season 4
The entire Moonlit Isle becomes invaded with evil spirits from the abyss. As a seal and ritual of healing was being performed on Kagura who was still possessed by Orochi, Daisy accidentally had entered the seal and the demon was passed unto her. As Ace is about to slay Orochi, Lu Bu takes the sword and slashes him himself, blood splattering unto him. Orochi is defeated but Daisy's curse has now passed unto Lu Bu.
