Marin Kitagawa

The heroine of this work, born on March 5th. She is a gal in the same class 1-5 as Wakana, and is slightly taller at 164cm. She lost her mother to illness at an early age and was raised in a father-son household. Her father was transferred before Marin started high school and lives alone most of the time.

She is a beautiful girl with a bold personality who is not afraid of anything. She is also active as a reader model and is so popular that she is often begged by her agency to become an exclusive model, but she does not let this go to her head and is also kind enough to care for others without discrimination. She is often hit on because of her looks, but she is basically cold to those who approach her, and she ruthlessly cuts off anyone who makes a mockery of what people love, whether it's herself or others. Wakana often teases her for her "action-oriented" nature, as she tends to act on her thoughts immediately. However, she often misunderstands the characteristics of her character and mistakenly books a love hotel thinking it's a photo studio, showing her rough and ready side. She doesn't particularly mind being seen in her underwear by Wakana, but she is extremely embarrassed about not wearing color contacts over her camisole, showing that her sense of shame is slightly off (although there are normal cases where she is embarrassed about being seen in certain underwear). She is also a big eater when it comes to food, and she often eats a lot, prioritizing substance (i.e., quantity, taste, punch) over appearance.

She has a strong otaku hobby, enjoying a wide range of anime, manga, and games (including adult games), and she doesn't hide it at all. Her room at home is covered with posters of her favorite characters, making it look like a painful room. She loves cosplay so much that she describes it as "the ultimate love," and she debuts as a cosplayer "Marin" after meeting Wakana. She pays for the materials and technical fees for the cosplay costumes she asks Wakana to make. After meeting the Kaga sisters, she is increasing her reader model work to buy an expensive single-lens reflex camera (again, her criteria for choosing a model is simply that it has the same initials as her). The transformation brought about by makeup and cosplay is at a considerable level, and people outside her circle of friends hardly ever recognize her as a model. When she cosplays, her gear goes up even more, and the finished photos are so impressive that they surprise and awe the viewer with their "possession/personality change" level of transformation.

In contrast to Wakana, she is quite clumsy with her hands. She is not good at sewing, and the cosplay costume she first showed to Wakana in the school's clothing practice room was not at all basic in sewing and was severely criticized by Wakana. Her cooking is not bad, but her plating and menu planning are quite rough, and her menu is "brown" with mostly meat. She also can't apply false eyelashes well by herself, so when she cosplays, she asks Wakana to do her makeup. She can't swim at all and is a hammer, but she likes the sea.

On the way home from her first cosplay event, she started to have feelings for Wakana when she said, half in her sleep on the train, "You were very beautiful" (after being told that she couldn't say it unless she really thought so). After realizing her feelings for Wakana, she started to approach Wakana aggressively, just like she did with anime and manga, but Wakana didn't notice at all.

Even when she thinks Akira is avoiding her (at first she misunderstands), she doesn't care, and even when Juju treats her coldly, she laughs off his attitude. She was initially like this with Wakana, occasionally teasing him because he was immune to girls, but as she fell in love with Wakana, she became so timid in love that she couldn't even face him directly.
