Reimu had taken to biting people again and we couldn't quite piece together why. She usually bites herself, being unaware of the self-injuries. If she isn't biting herself, then she is biting someone else. If she isn't biting, she's hitting or scratching. Of course, her self-inflicted injuries didn't come from just biting, as recently, she's scratched her face and even gave herself a bruise under one of her eyes. However, her harming others did create some sort of aggregation amongst everyone, besides Kaguya and Mokou's marifana hijinks and Ren's hair getting cut off (he's rather forgiving towards that), especially between her and the other children, more noticeably Chen.
When Reimu hits, bites, or scratches her, Chen returns the actions but it bounces off of Reimu, as she gives no reactions. Naturally, we have to remind them both not to hit. Chen resents this but Reimu, it seems, understands but doesn't remember the message when we disallow her to harm herself. We don't want her to harm others but, at the same time, we don't want her to hurt herself. However, Kaguya brought up the thought that Reimu herself, mental wise, cannot acknowledge that she has an injury, thus she's prone to ignoring it but her brain, sensory wise, doesn't. Ren pointed out how that doesn't make sense as to why Reimu harms everyone else, to which she said, "Well, she cannot acknowledge her own injuries but it could be possible that hurts others because she cannot acknowledge the fact that she is injuring herself."
Mokou, however, proposed a different theory, in that she only causes others pain because she knows they can respond to injuries and is probably trying to grasp what was conditioned from her and is probably trying to relearn what has been lost or, rather, cannot seem to grasp that everyone can and will respond to injuries and pain if they feel them, whereas, she won't, unless someone else responds to her being injured, in which case, it will click in her mind that somethings needs some attention and that is the only circumstance. Aside from that, her brain responds but she remains ignorant it. On top of that, Kaguya did bring up the fact that Reimu probably resorted to self harm as a way of coping while we were imprisoned.
Nevertheless, we wanted nothing more than to quell this habit.
"MOMMY!"
