A coworker named Nagumo is extremely messy, failing to maintain personal or environmental cleanliness. Despite this, his body odor has an effect on Konishi, making him feel calm and secure. The reason behind this reaction remains unclear. Separately, a boy named Michiya frequently gets into fights at school, driven by a desire to grow stronger in order to protect his neighbor Natsuki. Natsuki has had asthma since Michiya was young, but is now a high-level salaryman.
