Kokoro Fandom Guide

From Kokorodatabase

Kokoro Fandom Guides are very popular items in the dimension in which Kokoro is a TV show. A few have made their way into the hands of characters; Nakagawa Daichi and Shimizu Arisa each have one. Shirogane Ryou once had an Ichi-specific character guide, but she stole it from him and presumably destroyed it once she learned how accurate it was.
