The Blue Hue of Manga

The Blue Hue of Manga summary:

(from ebookjapan):
A blue kaleidoscope held by a boy next to me on the express train to Sendai. What he saw when he looked through it was the nostalgic world of his youth. In addition to the title story, "My Norakuro," "Tokiwa-so Charamera," "The Day Osamu Tezuka Died," "Ogawa's Medaka," which describes a summer vacation with his sons, and other autobiographies are included in this short story collection. Also of note is "Like the Wind... Insects That Ran Too Far Back", a retrospective of his relationship with Osamu Tezuka, including the "Help with Workd..." telegram and the feud over "Jun"!
