Matenshi

Matenshi (魔天使) is a humanoid of some kind that bares the resemblance of an angel and is the stage 4 midboss of Story of Eastern Wonderland twice. She attacked Reimu Hakurei and Genjii after they've flown passed some crows and other stage enemies as they approached her. She's got 5 different types of shots which are: single strand shots right below, random shot spread below, homing shots, some lasers and some 5 way bullets. The official strategy guide states that getting the former 3 is considered lucky. She does this again a while later after she was defeated the first time. With having no dialogue with Reimu, there is nothing known about her.
