I'll start by saying this; This is not a Review for Kidou Senshi Gundam-san, but this is a review for Gundam Sousei, which in my opinion has been stupidly included and listed as part of this series.
The story for Gundam Sousei dramatizes the origins of how the well known franchise of Gundam started. Naturally because this is the origin of Gundam the story focuses around a group of people pushing for the success of the series. The people included are; Yoshiyuki Tomino the Director of the series, Kunio Okawara the Mechanical Designer, Shūichi Ikeda the Voice Actor for Char Aznable, Yoshikazu Yasuhiko an Animator
for the series, Tōru Furuya the Voice Actor for Amuro Ray and many more (Check the Gundam Wiki for the rest). The feels very true to what it is meant to be, it may be dramatized and exaggerated in some places, but it is all still routed in reality, and conveys the struggles of the creators. Additionally the story is the only other one I have seen to detail the anime & manga industry, the first one was Bakuman. Lastly this is one of the few series I actually wanted to read in silence.
As for the art for it, is really great and helps convey the story really well.
The characters are 100% relate-able in at least one aspect or another, I won't go into detail, as I don't often write reviews, I'm not used to talking about characters personality. I can say for certain though that the characters being that they are the real people who worked on the original Mobile Suit Gundam, with some exaggeration here and there, it feels like you are getting an insight to what they're like or were like at the time.
If you couldn't tell already this series is fully enjoyable, and definitely worth a read if you're a Gundam fan or just want some insight into the industry.
Just read the series, it's 24 Chapters long, if you can get physical copies do get them. Also to the admins please make Gundam Sousei a separate page.
