(01) My Tranquil days are Over

Sakamachi Arata Wants nothing more than to spend his days as an average High Schooler. Eating lunch with his friends, Walking home from school with his childhood friend, Filling in his study quota and play video games until morning. To him these peaceful and uneventful days are the best thing in the world.

.....but all of that WOULD BE STRIPPED AWAY FROM HIM ONE NIGHT WHEN HE IS ATTACKED BY ASSASSINS AND SAVED BY A CUTE GIRL
