“As expected of our captain, a masterful decisive charge!” The ideal death!…Or so it was supposed to go, but thanks to his subordinates(?), an unexpected meteoric rise! A death-wish genius officer stirs up a rags to riches space opera, opening! Having chuunibyou and getting NTR’d by his girlfriend made the late bloomer Ensign Nao strongly aspire to that situation of [“protecting comrades and dying heroically”]. However, contrary to expectations, in the Capital Region Guard [Coast Guard] where he was assigned, he becomes hugely active thanks to his sharp mind and the unit’s problem children(?)! In a desperate close combat situation where he was supposed to die a [hero’s death], his subordinates annihilate the enemy in the blink of an eye! When encountering space pirates, he plans to stay behind on the ship for a su*cide charge but they succeed in capturing the enemy ship due to engine failure! Though troubled by the demonic unfeminine executive officer and the combo of a mecha maniac and musclehead female sergeant major, one month after taking the post he earns a promotion and exceptionally becomes acting captain. What’s more, it seems he’s found favor with the princess(?)… A death-wish genius officer stirs up a rags to riches space opera, begins!
