Balam Shichiro is one of the staff of Babylus Demon School. He was first introduced subbing for a faculty member in Demonic History due to his Evil Cycle. He is also the head of the Imaginary Things Research Division.
Shichiro is a giant and muscular demon, towering over even the tall Naberius Kalego. He has bird-like legs from his knees down at least, and long hair.
He wears a dark tank top, light colored pants, leather gloves, and a mask over his mouth and nose, covering an injury that exposes the left side of his jaw and fangs.
In Chapter 66, he cuts his hair off into a buzz-cut, claiming it scared the students and he didn't want them to be more afraid of him than they already were.
In Chapter 182, his hair grows back, but it is not as long as before, reaching only his neck and covering his ears, his hairstyle is very similar to the one he used when he was a child and when he was a student.
Despite his terrifying appearance, Shichiro is very kind and gentle, treating every living thing with compassion and a soft hand. He is also fascinated in the human world and the supposedly mythical creatures he believes exist there, becoming elated when he discovered humans exist after meeting Iruma.
He is also extremely protective. Upon discovering Iruma was a human living among the demon realm, he scolded the boy for being so careless, and ranted to him for hours about all the dangers he could get into and how to avoid them. He also continues to check up on Iruma thereafter, making sure the boy was staying out of trouble and ensuring that no one else had found out his secret.
Not much is currently known about his his past other then the fact that attended Babylus with Kalego. Both attending during the same year. It was revealed in chapter 182 that he got the scar on his face after he was abducted by a bird monster. After spending a night hiding in the nest, he tried to eat the eggs there with him, only for the angry mother bird monster to return and scar his face. His parents arrived in the nick of time to save him. Balam says that this event was when he recognized the beauty in living things.
Buzzer- His Bloodline Magic. He is able to detect anyone who is trying to lie or do wrongdoings by just observing them.
Aggressive Skinship- A defining habit of Shichiro, which makes the students at school suffer from massive uncomfortableness. He has a mannerism in grabbing creatures or in most cases, his students, and pet them for quite a while. This usually results in students running away in fear of him and spreading false rumors that he was doing that in order to find experiments.
Summoning Vines- One of his mostly used Non-Verbal Plant based magic. He uses them to take him places or grab anything nearby.
Iruma Suzuki- Shichiro was excited to discover that Iruma was a human. However, he was very concerned for him due to his lack of knowledge in the Demon World and the danger that lurks beyond the school. He provided the help that Iruma needed to pass his final exam, and was proud of him when succeeded in doing so.
Naberius Kalego- They were in the same class at Babylus Demon School as students. They are very good friends to the point that they are in the first name basis.
- He is one of the few Demons who knows about Iruma's status as human.
- He loves children's picture books so much that he makes them as a hobby. He is shown to have made Iruma several picture books to learn for the exam.
- He also loves cute things.
