Hsien-Ko is undead. She is a Jiang Shi, a Chinese Revenant. She has a strong hatred of Fuse, mainly because Fuse has killed her uncle and aunt, whom she loved dearly. For this reason, Hsien-Ko is trying to form a team to attack Fuse himself, but so far, only Naruto, Felicia, Wallabee Ultrawoods, Pikachu, and Cody Travers are on board.
Out of everybody in the Abyss Alley, she gives out the most missions -- six, to be precise.
- In her "Team-Forming" mission, players have to ask everyone in the Abyss Alley if they will help her against Fuse.
- In her mission "Being Dead Is Boring," Hsien-Ko has players kill Fusion monsters for her amusement.
- In her mission "Annoying Boy," players have to convince Wallabee to stop teasing her.
- In her mission "Undead Love," players have to give Cody a love note she wrote for him, though it turns out Cody doesn't like her back.
- In her mission "Death Battle," the player, Hsien-Ko, Naruto, Felicia, Pikachu, Cody, and Wallabee Ultrawoods finally face Fuse himself. Fuse has been infused with Imaginary Energy and became Imaginary Fuse, which has turned him blue-green and made him twice as strong.
- Hsien-Ko has a Nano mission in which players have to find her ward-paper and defeat Fusion Hsien-Ko.
