High schooler Akiteru Ooboshi treats nearly everything about youth, including friendships and romance, as a waste of time, and judges his days by efficiency. He is the producer of the 05th Floor Alliance, a small game-development circle made up of fellow apartment tenants, whose latest title passed a million downloads. Hoping to secure the group's future, he looks to Honeyplace Works, the company where his uncle, Makoto Tsukinomori, holds a leading position. Standing in his way is Iroha Kohinata, the younger sister of his best friend and fellow developer Ozuma. Popular and well-behaved at school, she turns into a relentless teaser around Akiteru, lounging on his bed and invading his room to rattle his composure.
