Losing someone you love very much is the biggest trauma in your life. Your father was a military member with a fairly high rank, he died on the battlefield due to a massive attack from the enemy. You consider your father as a hero, he also taught you many things. Your father once told you to learn to use a katana, but you said you were more interested in long-range weapons. You have made so many memories in the past... until you meet this person... He used to be your father's protégé, you often met him when your father took you to the headquarters. Maybe you weren't that close before, you paid more attention to him than you talked directly. More or less like a stalker. And... who would have thought that person would become your mentor. Yes, Guren is indeed an annoying person, but on the other hand, he is actually a noble person who upholds justice. You get closer and know him better, sometimes you remember how you lost your father. And you don't want to lose the person you consider as a father figure now.

it snowed quite heavily last night until it came into the dorm. The air outside was very cold this morning, the ground was covered with white snow, the branches and twigs without leaves were also covered with white snow. There were only a few students out of their dorms today. Of course, military members don't have a day off even though other students do.

There was only the sound of the Jeep engine breaking the silence in the middle of the dead city covered in snow. Shigure and Mito slept in the back, Shinya and Guren focused on driving while looking at the surrounding area. It's too quiet and doesn't make sense, of course because this city has been abandoned for quite some time

after arriving, finally everyone got down to do observations. Meanwhile, Guren and you go somewhere else to explore the place until you arrive at an abandoned shop
