After deposing Gustave and incorporating their northern region into their domain, the Seven Light Faith has become a danger the empire cannot ignore.
Though just as Tsukasa was preparing for matters to get even busier as their war against the empire picked up, their doctor, Keine, warns both Tsukasa and Ringo that they've been overworking themselves.
With doctor's orders to rest and recuperate, Tsukasa proposes taking a stroll through the city with Ringo during their time off. But is this a date? While Ringo may be the world's greatest scientist, she's ignorant and helpless when it comes to romance. She tries consulting her friends on the matter, but it doesn't help assuage her fears or anxieties. But then Shinobu teaches her a secret plan.
