A Stiff Smile? My Roommate is a Princess!.Towa, who is enrolled into Noble Academy under the name Towa Akagi, is put in the same room as Kirara. On top of trying to teach Towa to learn how to do things without servants, Kirara's workload is increased when she gets the chance to be a regular model on a new fashion magazine. While juggling all of this, Kirara grows concerned that her smiles are becoming forced. After stumbling across a serene pond nearby, Kirara teaches Towa what it means to smile, realising what she herself had forgotten in the process. With both girls feeling refreshed, the two team up to take down a Fashion Zetsuborg created by Lock.
