Shawn Nishizumi Williams in Ooarai highschool.

We are going to search for tanks? Really.

Student Council informs everyone that it has been a few years since sensha-dō was discontinued in Ooarai, but the other four tanks should still be around somewhere. Unable to give them more precise info, they encourage everyone to start looking for the missing tanks before next morning, when a sensha-dō instructor will arrive. Saori seems dejected, but when Anzu tells her that the instructor is "really cool", she immediately regains her enthusiasm.

As Saori, together with Hana and Miho, begins looking around for a tank (in a parking lot first, as they are "both vehicles"), Miho notices a girl following them from a distance, apparently shy for some reason; when she turns around and asks her if she'd like to search for tanks with them, she seems very happy and introduces herself as Yukari Akiyama. Oddly enough, she seems to already know who Miho is. But she doesn't her cousin shawn n Williams.

Shawn: Hey stop Following us.

Miho: Huh?

Shawn: Autistic child is following us.

Yukari: HEY I AM AUTISTIC.

Miho: Shawn stop calling other people with some kind of mental illness.

Shawn: Fine!

Yukari: Thank you

Miho: Do want to come looking for tanks with us?

Yukari: Are you sure!

Shawn: What the fuck cous.

Yukari: Um, I am yukari akiyama from standards education class 2-C. I am a complete rookie, but I'll do my best!

Hana: We're glad to meet you, I am isuzu hana.

Saori: I am Takebe Saori.

Miho: I am-

Yukari: I already know you. You're lady nishizumi miho, aren't you?

Miho: I.. am.

Shawn: Hey I am Shawn Nishizumi Williams, and cousin of miho nishizumi.

Yukari: Shawn Nizishumi Williams? I never heard of you but if your her cousin then. I am glad to meet you.

[As she salute like soldier.]

Shawn: Did you serve in the United states marines?

Yukari: No Don't haven't served in the United states marines.

Shawn: Tell me How the fuck know about the military. But you didn't served in one?

Yukari: Well I am military fan.

Shawn: You did play call of duty 1,2, and 3.

Yukari: No, I don't play games what  am I a gamer.

Shawn: Well I thought you are?

Yukari: No!

The first-year students are seen in a library, wondering where the tanks could be and why sensha-dō was discontinued. Back with Miho and the other girls, they are in a forest, when suddenly Hana senses a faint smell of iron and oil mingled with that of the flowers (to the others' amazement, apparently thanks to her flower arrangement experience which has enhanced her sense of smell); they quickly find out it belongs to a Panzer 38(t), to Yukari's excitement, so much that she blurts out all the tank's history and characteristics, only to excuse herself when she sees the other's puzzlement with her behavior. As they phone the Student Council about their discovery, the other tanks are being found: The members of the defunct volleyball club find a Type 89B in a cave on a mountainside, the history buffs discover a StuG III sunk into a lake, while the first-years locate an M3 Lee in a warehouse, used by rabbits as their home.
