Serving as the home economics teacher of Spooksville High, Mr. A is somewhat of a highschool legend - a hero to the misunderstood outcasts whose sparkling wit he understands, and an annoyance to the popular crowd that he never lets slide for things everyone else would get in trouble for, and to the overall student body, a laidback guy who never takes anything too seriously.

Most other teachers get along fine with him and love his dry sense of humor, but some of them feel he takes things a bit too far... Mainly the French teacher, Mrs. Erica, who he can't seem to stop teasing. When socializing with other adults, he is received as someone... Perhaps far too familiar. He is certainly friendly and kind, but he is quick to tease, and comes on a bit strong with other people. He really has no idea he's doing it, he doesn't know better unfortunately as he's largely had to raise himself alone and he's managed not to talk to a single therapist at any length even once in a thousand years, but it's still how he comes off. He very much means well! He just has to learn to do well too

... Unbeknownst to everyone, he is a deeply depressed person.

Mr. A was born to a nest of tengus in the 1100s - as you can imagine, he never knew Soujoubou, but they were born at around the same time. Tengus, born from giant eggs, are susceptible to birth defects and variation just as any other species is - and Mr. A was considered defective at birth.

He was smaller, weaker, slower than his siblings. He took slower to things he was taught, and he never even learned how to fly. His wings were much too small. He was immediately recognized as one who probably would serve more as a burden to the family as anything else. They didn't leave him to the wilderness as an infant, but after a few months when they were certain he knew how to find his own food, he was abandoned. The entire family simply packed their things and flew away while he was sleeping.

It went without saying that Mr. A became a mess of abandonment issues in his youth and early adulthood, emotionally traumatized and constantly in danger from larger predators, but he had one thing that went in his favor. He, being a tengu (even a runt), was to be considered the god of the mountain he was left on. This went fairly well for him as one would imagine, and he got a chance to mold his own personality despite the pain welling up inside him over his abandonment, until his abrasive, trickster-like personality ended up offending the wrong person.

Arikura-no-baba in particular didn't like his rude joking, his offensive friendliness, so she laid a peculiar hundred-year curse on his eyes. Anyone who was to make eye contact with him would fall desperately in love with him, dependent on his word in forming their self-esteem and self-worth, leaving him with the burden of many years of breaking hearts and hurting people until he shaped up... It was the perfect punishment for an insensitive person! But... The punishment didn't work.

It didn't cause Mr. A to realize he needed to become kinder and more gentle, the shock of the idea of causing so much pain to so many people simply... Caused him to isolate until his term was up.

However, when Ame-Amerou Amaoto came into his life, Mr. A began to be able to build up the confidence and strength (well - to an extent) that years of being cursed with such a burden had sapped of him. He'd lost the ability to make eye contact with people talking to him, he'd become softspoken to his own detriment, a doormat - but Ame was not affected by Mr. A's curse.

Ame had strange eyes as well, ones that constantly spun, slowly, in his skull, making him effectively blind.

This instilled a sort of trust in Mr. A, and so the two of them began to cultivate a friendship that was likely to last forever. Through this friendship, the two of them abandoned their responsibilities for many years (figuring there were enough mountain-gods and dream-eaters in the world) and made a living by conning the upper class.

Their exploits are quite literally the stuff of legend, but these are fairly obscure legends and Mr. A and Ame aren't known to confirm or deny any rumors brought to their attention. They like to keep people guessing!
