The Cure Is to Stack Critical Hits

Also known as The Stay-at-Home Dad Who Doesn't Want to Be a Pastry Chef Isn't a Good Jujutsu Sorcerer, My Healing Hurts, Bear With It, and Would Your Superiors Dare Hire a Stay-at-Home Dad Like This? Here's the more serious blurb. Kurikara Shunchi has a dream: to open a bakery of his own and see every customer smile with happiness after tasting delicious bread. So he studies hard, takes part-time jobs, and even sells handmade treats on the street for pocket money. After years of effort, the year he graduates from middle school, a teacher from a certain religious technical college discovers him and enthusiastically invites him to enroll. Kurikara Shunchi: ...? He looks at the man, currently as burly as a gangster's enforcer, but carrying an ugly-cute wool felt doll on his back and claiming to be a teacher at that college, giving off an extremely charming contrast. He smiles awkwardly but politely. "I'm not religious." In the end, he enrolls anyway and learns that his ability is exceptionally rare. Kurikara Shunchi: Still, I don't think this is a good idea. Why is his ability to restore people's health by punching them? Won't seriously injured patients get punched to death?? Shoko Ieiri, a fellow medical worker: It's fine. This is a good way to teach them a lesson. So, in order to boost the amount of healing he could do, Kurikara Shunchi went further and further down the path of the close-combat healer. Later, as Kurikara Shunchi gradually understood everything: "What? There are lots of injured people? Fine, gather them all together. I'll pick a lucky one at random and hit them with a Black Flash." The injured: Don't come near me!! Head hurts? Punch the head. Foot hurts? Step on the foot. Internal injuries? Hit the stomach. Pain is proof of life. He, Kurikara Shunchi, was chosen by fate to save lives, and he would do whatever it took, even if the injured went insane from too much pain! But... After his violent treatments, Kurikara Shunchi expected everyone to avoid him. Instead, he discovered that some people were actually coming to him to get beaten up?
