Koutarou Satomi's life took an unexpected turn when he moved into the suspiciously affordable Room 106 at Corona House, only to find himself entangled in a fierce battle for the room against a group of invading girls. As their shared daily life unfolded, old rivalries gave way to genuine bonds, and Koutarou emerged as the irreplaceable pillar of the group. Easygoing and thrifty by nature with a knack for mischief, he nonetheless rises to every challenge with knight-like resolve — and in time, reveals his true identity as the legendary 'Knight in Blue'.
