Takeshi Nogami

Takeshi Nogami is the illustrator of the Marine Corps Yumi manga.

Background
Nogami started his professional mangaka career with Koutetsu no Shoujo-tachi (a.k.a Panzerfraulein) published by Kadokawa Shoten, which due to various circumstances, was canceled by the publisher after volume 4.

Now, his activities include Sailor Fuku to Jyuusensha, a comic about tank-riding high school girls published by Akita Shoten; Tsuki no Umi no Rua, a comic inspired by Kaguya-hime tales in a World War II setting, from Shonen Gahosha; and the comic for Moeyo Sensha Gakkou!!, a semi-educational book about tanks from Ikaros Publishing.

As visible in his portfolio, he seems to be inclined towards military-themed stories.
