Kaygema Shigeo’s third emergency contact had become something of an enigma at Salt Middle School.

The office had raised a fuss about it, when they’d originally been inputting his information into the school’s computer. The rest of his registration form had been completed perfectly, almost meticulously, with allergies, medications, home, mobile, and work phone numbers and such all filled in. All of it was perfect, except for two small details: firstly, under ‘medical conditions,’ the word ‘ESP’ had been written in the deliberate, wobbling handwriting of a child. (The issue with this one was resolved about a week into the school year, with the Flying Stapler Incident of Class 1-3.)

The second oddity, however, was more persistent. In the third box for emergency contacts, written in the same handwriting, was ‘Reigen Arataka’, along with a phone number. The box labelled ‘relationship to student’ was conspicuously blank. The office had intended to raise the issue, but between the Stapler Incident and the fact that nobody ever actually used their third emergency contact, it was quickly forgotten.

Until the day that Reigen Arataka showed up in the middle of the day to sign Shigeo out of school, and suddenly, the man was the talk of the break room. Over the course of three days, some teachers plied the office secretaries with enough baked goods to learn that Reigen Arataka had come across as odd, if somewhat charming, that he’d tried to sell them all some sort of ‘group massage discount,’ and that they thought, possibly, that someone might’ve overheard Shigeo call him ‘Shishou.’

The mystery continued.

“Do you think he’s the real father?” The suggestion had come from Miyu Satoh, one of the 3rd year teachers, during an after school grading session. The general consensus had been that they couldn’t possibly have been related–after all, most of them had seen Reigen by this point, waiting outside of the school gates for Shigeo with a grin and a wave, and they all agreed that the two bore absolutely no familial resemblance. Besides, the year 1 teachers had all met the Kageyamas and their nice, mild-mannered younger son at the school’s open house, and there had been very little doubt as to whether the four were all related.

It was unusual, but for most of Shigeo’s first year, it just became a routine: start school day, teach, go to lunch and find out that Shigeo had been picked up early by Reigen, keep throwing around conspiracy theories about Reigen (the latest popular idea was that he was from the government, testing Shigeo’s ESP abilities,) break up a fight between some of the troublemakers (shame about Onigawara, they agreed after the third disciplinary warning, kid had real promise but he was determined to toss it out,) listen to Shigeo’s teacher, Toyoda, lament about how a thirteen year old could possibly not know basic algebra, teach again, grade papers, go home.

Shigeo had squeezed by with passable grades, and the next year, was placed into the class of Katsuko Kano.
