Crossing distant times, crossing the Gate, and spanning the world, I present to you my humble work, Geeto SEASON2: Jieitai Kare no Umi nite, Kaku Tatakaeri, which is once again receiving an anime adaptation.
This story is a world I spun stitch by stitch, pouring my heart and soul into every word. To the production staff who are breathing brilliant life into it with the power of art, sound, and voice, I offer my inexpressible gratitude.

GATE: Jieitai Kare no Chi nite, Kaku Tatakaeri, produced by Director Kyougoku Takahiko and A-1 Pictures-sama, became a memorable and talked-about work, not only for military enthusiasts but for everyone.
Now, the stage shifts from land to sea.
And that baton is being passed to Studio M2, who will be working with a new staff.
GATE SEASON2: Jieitai Kare no Umi nite, Kaku Tatakaeri
We are currently working diligently on production with the entire staff, having received cooperation from the Japan Maritime Self-Defense Force for research!!
We would be delighted if we could row out onto the great ocean together with all the viewers.
Please look forward to it!
Nakao Yukihiko (GENCO: Planning Producer)
It’s hard to believe that 10 years have already passed since the TV broadcast of the anime GATE: Jieitai Kare no Chi nite, Kaku Tatakaeri.
During that time, together with the original author Yanai Takumi-sensei, we have steadily built towards the realization of a second season anime adaptation, step by step. I believe we could not have reached this point without the passionate cheers and long-standing support from the fans.
And finally, we have reached the day when we can officially announce the production decision for the anime GATE Season 2!
In this work, GATE SEASON2: Jieitai Kare no Umi nite, Kaku Tatakaeri, the “sea” becomes a crucial theme as the new stage. To pursue realism grounded in reality and detailed depictions within the overwhelming fantasy world of the other realm, we conducted thorough research with the Japan Maritime Self-Defense Force. The entire staff is working with all our might to deliver a visual experience that vividly crosses the boundary between fantasy and reality.
Humanity, the other world, and the Self-Defense Force――
Please look forward to this new battle, where these three elements intersect once again, with an even grander scale and deeper drama.
