Female, 2nd-year Class A vice-president, and English department head. Due to her kind personality and mature aura, many students think of her as an older sister figure despite being in the same grade. However, contrary to her sharp impression, she is surprisingly clumsy. She can occasionally be seen loitering near the school warehouse just to look at an old computer running Windows 98. The doll she always carries is palm-sized with a TV for a head. Mare Flos doesn't just like non-humanoid characters (skeletons, mechs, full armor, object heads, or anything with electronics on their heads)—she is obsessed with them.

Female, PE department head, music department head, and a total Leokki-simp. Due to her usual lighthearted behavior, her classmates strongly perceive her as a "girl-crazy simp" or a "bratty elementary school boy." However, during music class, a new side of this beautiful girl emerges. She walks around with a long-tailed tit on her head and likes Leokki very, very much. She is rivals with Imuji to win Leokki's heart, and has confessed to Leokki approximately 1,230 times.

Female, Student Council President, a heartthrob for the girls, and full of responsibility. With her friendly yet responsible and shrewd personality, she has earned the trust and affection of teachers, seniors, juniors, and classmates alike. She is especially popular among female students. She has long pink hair and wears a pink clover in her hair.

Female, 2nd-year Class A president. Due to her haughty and cold aura, she has the nickname "Grand Duke of the North." Because of this, some classmates are too scared to approach her first and only admire her from afar. However, anyone who knows her even a little bit knows that she is actually closer to a "Pupu Duke." For the record, she had no intention of being class president, but ended up in the position due to someone's (Leokki's) scheme. She has a wheat allergy and effectively cannot eat any flour-based foods. Her favorite foods are milk pudding and rice noodles.

Female, 1st-year. She has a cute appearance with long yellow hair and a bear hairclip. Contrary to her gentle impression, she is a Leokki-simp. In other words, she likes Leokki extremely intensely. Because of this, she is rivals with Iomong to win Leokki over. Since they both share the surname Lee, others call them the Lee sisters. As a side note, she named the school cat "Imperator Caesar Divi Filius Augustus." The reason she chose this name is because it was the coolest-looking name in her textbook.
