My Heart's Yabai Yatsu Volume 4 Special Edition Deluxe Special Edition with Calendar & Illustration Card Set Filled with cute newly-drawn mini cards of Ichikawa and Yamada! Anna Yamada, a beautiful girl at the top of the school caste, and Kyotaro Ichikawa, a severely chuunibyou-afflicted, gloomy loner. Winter break arrives for the two, who have even exchanged contact information. Finally, the stage moves outside of school... A small smartphone connects them, a distance that feels near yet far, far yet near. Slowly, quietly, a strong heartbeat rings out, and then... the New Year's Eve bell. The Volume 4 Special Edition is hard to get! The special edition comes with a calendar and illustration card set from April 2021!! You can enjoy many beautiful "Boku no Yaba" color illustrations, and the calendar is filled with super cute newly-drawn mini illustrations of Ichikawa and Yamada!!
