Meira

Meira (明羅) is a mysterious female samurai that attacks Reimu Hakurei on stage 2 of Story of Eastern Wonderland, being the boss of that stage. She'll fire barrage of danmaku from her sword, where her last attack is shooting some purple and red bullets that reflects five times of the sides of the screen. Believing that by defeating the Shrine Maiden in battle, she'll gain the powers of Hakurei, she attempts to beat Reimu, but she fails and escapes, where Reimu wanted to bury her. She hasn't been seen since.
