Hamasaki Silently Devoured Her Sister Who H Link: Mao

Alternatively, the sister could be a non-Kamui user, which makes the devouring more problematic. If the sister isn't a Kamui user, maybe Mao would not be able to consume her in the original context of Kamui's rules. Therefore, perhaps this is a different context where Mao can devour anyone. But given the user mentioned Kamui, I should stick to the original rules. Therefore, the sister must have Kamui. So, in this story, maybe the sister is another user whose Kamui Mao needs to absorb to achieve her goal.
