The main setting of Cold Steel III, Thors Second Branch School is, at its name implies, a 2nd branch of Thors Military Academy founded by Prince Olivert and located in Reeves. It was created after the civil war with the intention of accepting students from the new provinces, as well as drop-outs from other schools.
It is headed by former Noble Alliance commander Aurelia Le Guin, whilst Michael of the Railway Military Police serves as Chief Instructor. Professor G. Schmidt also serves as a special adviser. As the main campus's Class VII was replaced with a traditional Class VI, it features a new Class VII, tasked with Special Affairs and taught by Rean Schwarzer, Class VIII, tasked with Battle Tactics and taught by Randolph Orlando, and Class IX, tasked with Accounting and Statistics and taught by Towa Herschel.
For tropes pertaining to Class VII, see here.
Warning: spoilers relating to events/reveals that happen during the first two games shall be left unmarked. Certain spoilers relating to the third game however shall remain tagged.
As a whole:
- Blue Is Heroic: In contrast to students from the original Thors, which now has black and red as the uniform's general color scheme, the students of branch instead wear two shades of blue.
- Cool Train: The Derfflinger which consists of six cars.
- Pink Girl, Blue Boy: Originally with the Panzer-Soldats as boys piloted the Blue Drakkhen and girls piloted a Pink Drakkhen during training sessions. This later gets thrown out the window with the arrival of the Hector, Kestrel, and later the Goliath Noa.
- Reassigned to Antarctica: The students who have enrolled at this academy are those who weren't able to enter the main branch - possibly because the higher-ups didn't want them on the same campus as the crown prince for a variety of reasons. Aurelia claims that it's the same for the teachers as well.
- Shipper on Deck: Nearly the entire student body ships Rean with Towa.
