Minami Shimada

Minami Shimada (島田 美波 Shimada Minami) is a major character, she is also a 2nd year high school student at Fumizuki Academy.  After living in Germany for most of her life, she returned to Japan. She was placed into Class F, although based on her academic ability, she could have been placed into other better classes. However, because she has spent most of her life in Germany, the language barrier has made it difficult for her to excel in school since her grasp of the Japanese language is still lacking. The one subject she does well in is Mathematics, because of the lack of Japanese knowledge required. However she is weak in other subjects because she cannot speak, read, or write in Japanese very well.

Shoukanjuu :

Her shoukanjuu (summoned being) wears a military outfit and uses a sabre.

Occult version is Nurikabe (wall monster), influenced by her flat-chest since "wall=flat chest".

During the Test Field Run, her shoukanjuu acted less like the real Minami, and behaved a lot like Hazuki, but only around Akihisa, while being disobedient to Minami. After Minami attacked Akihisa to keep the truth of her feelings for him from coming out, the shoukanjuu apologizes for her, suggesting that Minami herself doesn't mean to hurt Akihisa most of the time.
