Shounen Readom: Yuujou, Doryoku, Shouri no Uta
少年リーダム～友情・努力・勝利の詩～
Serialized in Weekly Comic Bunch, this brief manga was adapted from a non-fiction book written by a former editor-in-chief of Weekly Shonen Jump. While the publication is now called Readom in the story, the cover art style clearly echoes the Jump Comics designs from that era.
