However, while pre-serialization debut one-shots tend to see some sort of collected release if they were officially published previously, most often either as bonuses in volumes of said serialization or put together as a "tanpenshu" (literally "short story collection"), seeing a mangaka's actual amateur work published after the fact is immensely rare... which is what makes this review really neat.
As the final part of the 40th Anniversary of his debut as a professional mangaka, 2015 saw Masami Kurumada draw the manga Ai no Jidai -Ichigo Ichie-/Indigo Period -Once in a Lifetime-; yes, his 40th Anniversary was in 2014, but oh well. Running in Weekly Shonen Champion from Issue #33 to #41, & collected in a single volume, Ai no Jidai was unlike pretty much any other Kurumada manga in that it was a semi-autobiographical story about Masami Higashida, a young man who decides to try his hand at becoming a mangaka after discovering Hiroshi Motomiya's Otoko Ippiki Gaki Daisho and realizing that even an everyday ex-delinquent like him can enter the industry. As mentioned, Kurumada based Higashida's story on his own real-life one, though naturally fictionalized so as to make for a better, more interesting story, like having Higashida's two best friends go through their own respective personal hardships (life as a yakuza & on death's door due to illness, respectively). I read & reviewed Ai no Jidai back in 2016 & absolutely loved it, and thankfully in more recent time it actually received an English fan translation, so it's never been easier to recommend that people check it out. A neat touch in Ai no Jidai, though, was that Kurumada actually showed the cover pages to some of his initial amateur one-shots in the manga, with them acting as Masami Higashida's own work in the story, marking (to my knowledge) the first time they had ever been publicly shown in some form, since in real life Kurumada didn't win the single contest he submitted a work to, so he never had anything published until he made his debut in 1974 with Sukeban Arashi.
However, two years after Ai no Jidai's serialization, and a little over a year after my review of the manga, something really neat happened. When Akita Shoten published the October 2017 issue of Champion Red there was a bonus book included with the magazine, a rare but not unheard of thing with manga magazines. In this case the bonus book was Ai no Jidai BEGIN, which actually collected all four of Masami Kurumada's amateur manga one-shots in their entireties, with three of them being bookended with the pages of Ai no Jidai that indicated where they technically fit into that manga's story. For all intents & purposes, you could simply insert (three of) these one-shots into Ai no Jidai & they really wouldn't interfere with the overall story. Unfortunately, I didn't find out about Ai no Jidai BEGIN until long after that issue of Champion Red came out, and since it was never given a traditional release the book's kind of become a bit of a white whale for my personal collection of Kurumada's catalog, alongside Sukeban Arashi, Silent Knight Sho, & Akane-Iro no Kaze's individual releases (which are all similarly tough to get a hold of physically today, likely due to low print runs). However, much like how Ai no Jidai has now received an English fan translation, the same is true of Ai no Jidai BEGIN, so I can at least read & review this book. This actually is the very last of Kurumada's manga for me to write about that have absolutely no connection whatsoever to any of his major works, so let's finish (to some extent) things off by going all the way back to the beginning... in fact, it's the genesis beyond the beginning.
