Breaking down the characters of Jarhead in anime?

I think Nitori Aiichiro, Sakurako, and Armin Arnold are considered Jarheads. "Psychic 100%" by Shigeo Kageyama, Class 1, Grade 2, Shio Middle School, there is a pot lid. He has an ordinary appearance, is thin, is not good at studying and exercising, and has a weak constitution. Disbanding dangerous religious groups, suppressing gangs of delinquents, destroying and regenerating school buildings, fighting mysterious superpowers, and rescuing girls possessed by evil spirits, all caused various incidents. He is regarded as the founder of the "Super Jarhead Cult" with 580,000 followers, and is called "Riban Chang" and "White T Poison" by delinquent teenagers.

Karasuma Oji's "Busty Campus". The heroine Tsukamoto Tenma is obsessed with the boy she likes from beginning to end. This character and behavior are very mysterious and weird, with extraordinary power. Karasuma Ohji is a person who looks expressionless, and it is impossible to know what he is thinking in his heart. Even so, Tenma still likes him.

エンジュ/Enju/Anji "Border Prince". Young people living in other dormitories share a fascination with the past and are mysterious figures. One sister died. Although he is dead, he often feels that Yuta is very similar to his sister. His extraordinary skills seem to have something to do with the Grant family. The purpose of entering Saint Alfonso College was to assassinate Joshua, the successor of the Roland Principality. Later, he gave up the mission because of Yuta and saved Joshua instead.

Cherry's "Chibi Maruko-chan". The story naturally revolves around her interesting scenes with her family, friends, teachers and classmates in life and study. It’s about family, love and friendship between classmates. In episode 936 on December 29, 2013, Maruko-chan changed her hairstyle for the first time, which caused a heated discussion. She changed from the zigzag bangs to the current fashionable short hair, with the bangs pinned on both sides with two small hairbands. In episode 937, Maruko-chan's hairstyle has changed again.

Levi Ackerman's "Attack of 1.6 Meters". It is characterized by short black hair, white skin color, small face shape, three-dimensional facial features, frequent frowning, and dark circles under the eyes. His eye color is dark blue or grey-blue, and he has severe mysophobia. He wears a mask and hood when cleaning. He has very high requirements for cleaning. He wears an apron when interrogating prisoners, and wipes the stains on his body with a handkerchief after killing a giant. Despite this, he will hold the blood-stained hands of his subordinates without hesitation before they die, and solemnly promise to destroy all giants in the world. So I think these characters are considered Jarhead, and the above is just my personal opinion.
