Mayura Seno

Mayura Seno (瀬野 真由良 Seno Mayura) is the older sister of Alice Seno who has beauty and skill at everything. She is on the archery team with Kyô and excels in school. Perhaps her only flaw is her allergy towards animals. She loves Kyô Wakamiya, but, unlike Alice, she was able to tell him and worked hard to get him to date her. When Mayura realizes Alice loves Kyô as well, she tries to set Alice up with another boy. She vanishes when Alice accidentally wishes her away and the hatred in her heart makes her an easy target for the Maram Words. She becomes a Maram Master and tries to kill Alice and separate her from Kyô once he ended their romantic relationship due to his feelings for Alice.

Eventually, it is revealed that the darkness is Mayura's heart stems not just from Kyô rejecting her for Alice, but also because she felt hurt that Alice would not confide to her about her feelings for Kyô as well.
