- "That's it!"
- ―Hippo Team
Hippo team consists of history buffs or reki-jo from Ooarai Girls High School. The team operates a German StuG III, which they found on the bottom of a lake. They first painted it with multiple colors, making it look flamboyant and they added some banners on its engine deck.
About Sturmgeschütz III Ausf.F
The Sturmgeschütz III is a German assault tank with a powerful 75 mm gun; while its gun has limited traverse, its low silhouette makes it ideal for ambushes.
Against St. Gloriana
During the practice match against St. Gloriana Girls High School, Hippo Team managed to ambush and take out a St. Gloriana Matilda tank on a narrow road; however, they were hit soon after, as the height of their banners gave away their position from behind a fence, negating the advantage provided by the tank's low silhouette.
Before the 63rd National High School Sensha-Dō Tournament, the Hippo Team repainted their tank German Grey (Feldgrau) and added the image of a Hippo.
During the match against Saunders Girls High School, Hippo Team managed to ambush and destroy one of Saunders' two M4 Sherman tanks that had been lured by Duck Team. Erwin and Caesar can be seen with stunned expressions at the end of the match, after seeing Hana take out the Saunders flag tank from a long range.
In the manga, Hippo Team served as the flag tank.
In the OVA, Hippo Team was supposed to deal with Anzio Girls High School's flag tank, but it was instead drawn into a one-vs-one duel against a Semovente da 75/18 (commanded by Caesar's childhood friend Carpaccio), which, despite the StuG's edge in firepower and protection, ended in a draw, with both tanks taking out each other.
During the semi-final round match against Pravda Girls High School, Hippo Team's role was to hunt the Pravda flag tank; prior to the match they replaced their tracks with "winterketten" to make the tank more maneuverable on thick snow. Hippo Team managed to take out Pravda's T-34/76 flag tank after a lengthy chase by hiding under snow and waiting for it to come close enough.
During the final round match against Kuromorimine Girls High School, the Ooarai tanks managed to survive the initial attack by Kuromorimine, and they gathered on top of a hill and exchanged shots with Kuromorimine, later successfully executing a breakthrough. After that, they were lured by a lone Panzer III Ausf.J of Kuromorimine into a trap set by a super heavy Maus tank into the city. The Maus managed to take out Mallard Team and Hippo Team with its fearsome firepower. In the end, however, Ooarai managed to take out Kuromorimine's flag tank commanded by Maho Nishizumi and thus to win both the match and the championship.
Against St. Gloriana - Pravda Compound Team
Hippo Team participated in the defense of the OY-line during the match. In pursuit of Anglerfish Team, the column of Pravda tanks was lured around a blind corner and across an open plaza. Hippo Team, along with the rest of the Ooarai and Chi-Ha-Tan tanks, turned the plaza into a shooting gallery.
Once the OY-line was broken, Hippo Team found themselves in a chase along the beach, disadvantaged due to their vehicle's lack of a rotating turret. To compensate, the team attempt to execute a 180 degree drift to bring the gun to bear. However, the pursuing T-34 still evades their gun arc, outmaneuvers the now-reversing Stug III and takes them out from the side.
Against Selection University
In the match against Selection University, Hippo Team was initially a part of Team Sunflower. They took the high ground at the start of the match, but were unable to even fire a single shot before being forced off the hill by the powerful assault.
Some time afterwards, Hippo Team is seen joining the detachment at the eastern utility gate alongside other Ooarai tanks. They are amongst the tanks that are surrounded in the amphitheater, although they manage to escape alongside everyone else.
Hippo Team then led the efforts of "Operation Macaroni-Zwei", an Anzio-inspired deception that used cut-outs and disguises to conceal their tank against a suitable backdrop and ambush Selection University tanks at close range. Hippo Team knocks out two Pershing tanks whilst disguised as a vending machine and a brick wall, but on their third attempt, a dubious placement of a burger stand in front of a shop with Chinese markings gives away their position to Azumi, who fires first and takes them out.
