さんかく窓の外側は夜 (Series) favorite_border

[DeepL Translation - needs review] Introduction to Volume 1: A bookstore clerk, Sankaku, has always had the ability to see spooky things. Although Reikawa is a skilled psychic, he lacks emotional and life skills, so Triangle is often called upon to serve tea and "read the air". Then, he encounters a murder case... This is a psychic entertainment of the uneven duo!
