Celles Loublan

About
She is a third year at the school, most likely first noticed by Kaito Aiba in the dungeon being used by her classmate (Mitsuyo) as a mule.

She is a huge airhead who seemingly lacks common sense. Because of this she doesn't have that many friends and bullies take advantage of her. Despite this she is good friends with Ronnie Steinhart who seems very protective of her.

Despite being an Elf, she is incapable of any magic and just uses her bow instead. She lacks any confidence in herself. She is kind and never refuses a thing, she also cares for animals and is interested in the arts being a painter herself.

She is first met after she got bullied in the toilet. They took her towel, then her glasses when she looked for them and placed a bunch of stuff around so she would trip over it. Kaito gives back her glasses and helps her out.

It is revealed that she can't swim and Kaito decides to take her on some special private swimming lessons as learning at this age is embarrassing to her. They find a dungeon lake and practice without success. Kaito then shoves her in the deep end to force some danger and waits as she struggles, but she gets grabbed by a group of Kaniras and it takes too long. Kaito ends up saving her. Despite this, she sees his good intentions and trains hard. She learns to swim bringing her a step closer to graduation.

She gets tricked by her bullies, Gloria and Mitsuyo, into believing that Musel Clasmine and Kaito were kissing which hurts her a bit. She thinks her feelings are one-sided, apologizes to Musel for getting in the way and runs off alone in the dungeon. Kaito hears from Musel and figures it out and chases after her. She is distraught and tries to get away further but is too wounded to do so. Kaito takes her to the infirmary where they both confess.

During the christmas-like holiday (holy celebration of the birth of St. Musel), Kaito is sick and she comes over with a giant Nikuman and she tries (and fails) to make some eggnog for him. She then has sex with him which she prepared for by practicing and reading books (Ronnie's doing).

Her ending has them take the exam together which makes them narrowly miss out on a hostage situation caused by Kaina Shikido and Setsuna Shikido using spatial magic in the dungeon to find the soul vessel. Him and Celles go after them as Kaito wants to know what they are up to. They run into Setsuna which they beat, but Kaito gets tired out. Celles continues onwards by herself for him and her "friends". She confronts a reluctant Kaina who uses her bullies' lives to test if she really cares and allows himself to be killed by her if she so tries as he is seemingly moved by her feelings. She does so and afterwards they both graduate. She becomes a teacher and ends up marrying Kaito.

Abilities
She is an elf, but lacks any magical skill. She makes up for this by being a good Scout despite her airheadedness. She fights using a bow. She has arrows which are candy-tipped, the idea being that something sweet makes the monsters lick their wounds more afterwards and this will help them heal. Not all of her arrows are like that.

She also seems to have the makings of a good teacher and all she needed was confidence.
