The Natsu no Arashi! official website has recently updated with full staff and cast information, listing the production studio as Shaft (Sayonara Zetsubou Sensei), and Ryouko Shiraishi (Kemeko Deluxe‘s sword-wielding Ryouko) as the female lead Arashi.
The Natsu no Arashi! manga is Jin Kobayashi’s second published manga serialization and his follow-up to School Rumble, which recently finished in 2008.
The story deals with thirteen-year old Yasaka encountering mysterious sixteen-year old Arashi, a girl with mysterious powers who is on the run from assailants who takes up residence with Yasaka. As a supernatural / love comedy story, it might be appealing to those who would enjoy a different sort of story from Kobayashi than the more gag-centric School Rumble.
