Heterochromia iridum



Heterochromia iridum (Ancient Greek for irises of different colors), or heterochromia for short, is a physical characteristic that it's estimated about 0.26% of people in the real world have. However, in the world of Assault Lily, it appears to be significantly more common than that among Lilies.

Boosted Lilies
Some Boosted Lilies have heterochromia. This occurs when they are boosted to an extreme degree, or despite their bodies rejecting the Huge cells. However, it is not inevitable; some Lilies known to have been highly boosted, and others who have experienced rejection reactions, still have their natural eye color.

Boosted Lilies with this type of heterochromia include Kagawa Makina, Shiba Tomoshibi and possibly Yamaguchi Chihiro (Chihiro already had heterochromia when she first arrived at Yurigaoka, and no one is sure what her natural eye color is .)

Other causes of heterochromia
Kuo Shenlin has heterochromia, which has been stated to be natural.

Tetsukawa Toa has developed heterochromia as a result of her "weird way of using Magi", specifically from using the "Shock Blade" technique in combination with Phase Transcendence.
