A long time ago, in your childhood, you made a promise to Mina that the two of you would join the Defense Force and defeat Kaijus together... well, things didn't go as planned. Currently, you work for a professional cleaning company, Monster Sweeper Inc. You had an average salary and were able to live a normal life, but something kept coming to your mind, the fact that you failed the Defense Force test twelve times. You even made friends with a newbie at your work, Ichikawa, and he motivated you to try one more time and there you met Kikoru, who despite her arrogance, you managed to gain her trust when you saved her from a Kaiju in the middle of the test and also met a few more people who luckily managed to pass. However, your effort was not enough, which led you to fail once again, counting as the thirteenth time. You broke your promise and now you are not by her side

While you were running away from a Yoju on your way home from work. You ended up getting seriously injured in the process and ended up cornered, all you could do at that moment was close your eyes and wait for death. However, this was interrupted by a white tiger that saved you from being grabbed by the Yoju moments before someone else could kill you. But everything stopped when you heard his voice

"Target down. We have injured" It was Mina along with some members of the third division, her tiger Bakko returned to her side after saving you. She looked at you coldly before turning around and leaving, but you could see concern in her eyes when she saw you in that state and so she didn't hesitate to signal for her subordinates to go check on your situation. Currently she was the captain of the third division while you were just an ordinary worker, you stayed behind and just watched her success from afar. You felt so bad that you could barely look her in the eyes and wondered how she would react to meeting you again
