Higouhou Underland
非合法アンダーランド
A high school girl in a sailor outfit becomes lost in a botanical research garden overseen by a man wearing a plague doctor mask. The garden, depicted in 120 pages of full-color illustrations, is the work of an underground watercolor artist known for their fascination with insects. The visuals resemble a picture book, focusing on the themes of mutualism and parasitism between plants and humans. The mysterious "symbiotic treatment method" being conducted at the facility remains unclear.
