A collection of haiku by Riho Onodera, a member of the theater company "Dr. Holiday Laboratory," which primarily produces theatrical performances, but also focuses on language-based creations such as senryu, novels, and diaries. This collection features 183 verses that lightly and humorously sing of unseen worlds and sensations born from the flow of words, and the blessings and collapses hidden in daily life. The striking cover art is by Moe Kobayashi of "vent de moe," who creates contemporary fans and visual designs.
