Souichi's Diary of Delights(双一の楽しい日記) is the fifth entry to The Junji Ito Horror Collection, a 16 volume anthology of horror stories by Junji Ito. This volume centers around Souichi Tsujii(双一Tsujii Souichi), an eccentric oddball of an 11 year old who specializes in voodoo and enjoys causing havoc against various people. Unlike Ito's other volumes (except the sixth, which also features Souichi), this volume is considerably lighter and contains a touch of black comedy, rather than the usual horror.
