Tsutomu Satou

Looking at Miyuki and Tatsuya now, it might be hard to imagine them as anything other than loving siblings. But it wasn't always this way - Three years ago, Miyuki was always uncomfortable around her older brother. The rest of their family treated him no better than a lowly servant, even though he was the perfect Guardian, watching over Miyuki while she lived a normal middle school life. But what really bothered her was that he never showed any emotions or thoughts of his own. However, when danger comes calling during a fateful trip to Okinawa, their relationship as brother and sister will change forever.

El hermano “irregular” o poco talentoso y su brillante y hermosa hermana están por terminar el primer año de preparatoria en la Primer Escuela de Magia. Tatsuya, Miyuki y compañía deciden tomar un descanso aprovechando las vacaciones de primavera en una villa en isla Ogasawara. Todo es diversión hasta que una misteriosa chica llamada Kokoa aparece frente a ellos. Ella es una fugitiva de la Base Naval con un solo deseo... ¿Cuál es el deseo de la misteriosa chica? ¿Qué aventuras les esperan a Tatsuya y compañía?
