EX Rumia

EX Rumia is a pre-installed boss in Danmakufu and a upgrade of the Stage 1 boss called Rumia from Touhou Koumakyou.

Touhou fans think the ribbon amulet on Rumia's head acts as a seal on her true powers.

EX only appears when someone takes off the ribbon amulet off her head by someone that isn't her.

Appearance
In this form, she appears much more mature. She commonly wields a large sword (sometimes two of them) and freely manipulates darkness. She's also sometimes depicted as a adult and/or has black wings. It is also not uncommon to see her ribbon flying above her head in a similiar fashion to a halo.
