Shea appears in the following doujins:

-DESCRIPTION-
(info collated from google translate)

Nimi Shea, 18, is a young schoolgirl who can transform into a blue haired wonder rocking a bastard sword. She has a "Gravity Sphere" ability. She is described as having a low winrate; in every story involving her thus far, she ends up throughly defeated and violated. She has a boyfriend who is sometimes forced to watch evil men penetrate her little holes (p53, p14).

Shea's magical transforming item is a necklace that she wears under her normal clothes (see p22-23). She hangs out a lot with Nanai, another magical student. She defends the same city as Maki.

感觉作者故事有点跳跃... 凌辱又描绘得不够细致... 故事性和实用性都不太行啊...
