Dōjinshi (同人誌, often transliterated as doujinshi) is the Japanese term for self-published works, usually magazines, manga or novels. Dōjinshi are often the work of amateurs, though some professional artists participate as a way to publish material outside the regular industry.
The term dōjinshi is derived from dōjin (同人, literally "same person", used to refer to a person or persons with whom one shares a common goal or interest) and shi (誌, a suffix generally meaning "periodical publication").

Why I Collect...

No different from other Mawile Merchandise, Mawile is my second-favourite Pokemon, I love the design so much.
I collect these books because they feature Mawile as the focus.
I bought them just to own them basically, I don't actually read/view them.

None of the covers below are pornographic in nature, only the contents of the actual books are.
