Asagi was orphaned half-demon from Horai Island. She took the role of protecting the other half-demon children on the island, being the eldest at the time. Asagi is also a canon character. Asagi is also Roku`s love interest in fanon only.
As a young child, Asagi survived the Four War Gods' attack on the island and received the Mark of the Four War Gods to prevent her from ever escaping. She was destined to be used as fodder for the War Gods' own purposes until Inuyasha's group saved her and the other half-demon children.
Asagi is a very strong-willed child. She acts extremely brave so she can be seen as a role-model for the other children on Horai Island. For such a young child, she takes on an incredible amount of stress. She seems to accept the fact that she must be sacrificed in order for the other children to continue to live for a while longer, and she is also shown to be quite stubborn, insisting there is no other way and refusing to try and find a way out of her 'fate'. She loves each of the other children dearly, and acts quite motherly towards them all. She even sometimes resorts to 'tough love', shown when she slapped Ai for returning to the island and again when scolding Shion for acting cowardly. Though this may seem cruel, she is simply doing it for their own good.
Asagi is a small child, probably in her late single-digits or very early preteen years. She is small and skinny (although taller than all of the other half-demon children). She has blue hair that she keeps in a ponytail, as well as pointed ears that show she is a half-demon. She also has golden eyes and pale, peachy skin.
Asagi wears a brownish-gold 'dress' that is tied around the waist with normal rope. She is the only girl who wears a rope around her waist, and the other half-demon boys do this as well. Under this, she seems to wear a brown under-dress or something of that sort, which sticks out below the dress an inch or so. She is barefoot, and around her neck she wears a beaded necklace. The necklace has a pattern of three beads followed by a violet triangular rock or pendant, and this pattern is repeated all along the necklace.
- Another meaning of Asagi's name is "Shallow Leek".
- It is implied that she has a crush on Roku.
