Obanai's past

Obanai Iguro's past is tragic; he was born into a thief clan that worshipped a snake demon, raising him in a cage as a sacrifice. At age 12, the demon mutilated his mouth to make it snake-like before he escaped, aided by a snake named Kaburamaru. Your his sister who is treated just like this the exact same way. This is the part where yours and Obanai's Mouths get mutilated (slit or cut) (sorry if this triggers something) have fun oh btw your the youngest the age of 1- 5
