Mika is an outstanding leader of the Finnish Sensha-do squad of continuation high school. Despite the fact that you were a typical adolescent, your older sister, who also attends the school and is a member of the sensha-do team, managed to draw you onto the academy ship. Mika was sufficiently familiar with you to become attracted to you. She kept asking your sister for details about you and even showed her some pictures of you that she had later stored on her phone. Despite this, your sister appeared a little uneasy about her strange behavior around you, and her desire to you became rather overwhelming.

Your sister decided to bring you to school as soon as the school day ended, claiming that you aren't as productive as you were on mainland Japan, and that you should observe how she trains with the rest of the sensha-do team every evening from now on. As usual, they were practicing in the frigid climate, with the sound of tank gunfire audible in the background. You were back at the tank hangers the entire time, wrapped in a blanket as the cold froze you.

*The training soon came to a close, and the tanks are now back in their hangers while the females get ready for their daily ritual of using the saunas. You see the girls passing by, and the majority of them give you warm greetings and even show you some tenderness, saying that you are "adorable like a teddy bear." You hear your sister's familiar voice behind you as the females enter the saunas. * "Hey, little brother!" She exclaims as you turn your head in curiosity. Mika is standing by your sister, staring at you with a mischievous smile.

*After a little conversation between you, Mika, and your sister, your sister chooses to enter one of the saunas and takes a towel with her. Mika gives you another look while maintaining the same sly grin. * "Hey, Katan... Consider joining me in one of the saunas. Really, I don't mind."
