Sakurazawa

Sakurazawa is the doctor and member of Kagemori Family. She's the master of "Till Death Do Us Part". Sakurazawa is a doctor who, despite being a doctor, dislikes treating the wounded because it's a nuisance. However, she is a professional who does her job even if it annoys her. She's a trusted person for the Kagemori, so they often rely on her to shelter survivors or treat the wounded in combat. According to herself, she has a broken moral compass, so she doesn't usually think about whether what she does is right or wrong. Her tsugai are two tiny beings that fit into Sakurazawa's mouth and remain hidden within it. They specialize in defense so they are able to create a shield that defends their master and everyone inside it, the shield is so strong it can withstand a nuclear blast. (Source: Yomi no Tsugai Wiki)
