Sakuya Otsuki is the son of a legendary detective, following in his father's footsteps with his assistant, Lilithea. However, something's different about this high-school sleuth. Wherever he goes, he always manages to get himself entangled in his cases—as a murder victim. When Sakuya is tasked to infiltrate a luxury cruise ship, he finds himself killed once again. But every time he reopens his eyes, Lilithea is there by his side, ready to help him get to the bottom of the mystery…

What would you do if your crush had ear-splitting farts? For Aimi and Nami, the answer is to cry tears of joy for being able to pinpoint at a distance the object of their affections, Kirio, from a single toot. These are the kinds of deep, philosophical questions the two friends/rivals in romance pose to each other to prove their love for this boy who hardly seems to know they exist. That won't stop them from conducting nightly rituals to entice him into their dreams, though, or listing out what exactly they like about him, down to the very last organ. But when push comes to shove, will they choose their hilarious friendship over a shot at love?
