Touhou.pl ~Human meets Danmaku~

Stage 1 boss: Etanity Larva, The Butterfly Youkai Close to the Gods (Yes, her name has a different typo in her profile)

Species: Fairy; Power: To scatter butterfly scales

A Swallowtail Butterfly fairy. That said, she's not just the adult, but also the larva and the pupa, so you could say she's a growth and rebirth and metamorphosis insect fairy. Like Cirno, she's being powered up from how she normally is. She's gone berserk, so to speak. The incident, after all, is about fairies going berserk. She's normally very gentle, and even in battle she's more interested in picking up power-up items. When she senses danger, it seems she releases smelly danmaku from her antennae.

Boss 2: Nemuno Sakata, the Mountain Hag whose passed beyond this transient world

Species: Hag; Power: To consecrate ground.

Lives on youkai mountain. Hags are a solitary race that rarely interact even with each other, so naturally they don't talk to others much either. However, when they do interact with others they're extremely businesslike. They have an agreement with the tengu to give them their own space and leave them alone. It's often thought that people who disappear on the mountain were eaten by hags, but they actually send back the adults and adopt and raise the children. The reason is unknown. She herself has no interest in the world around her, and there's very little information on this uncivilized part of Gensokyo.

Boss 3: Aunn Komano, the Divine Beast who adores gods

Species: Komainu; Power: To find gods

A komainu with the nature of both a Shishi and a Komainu at the same time. Both Komainu and Shishi have a peculiar nature: they will seek out places where people worship, like the Hakurei Shrine, Moriya Shrine, or Myouren Temple, and decide to guard them on their own. It's in their genes, but they're not really all that strong, so they often lose. She was headed to the Hakurei Shrine for a flower viewing when the incident broke out. She'd only wanted to go get drunk and watch pretty flowers, but somehow ended up fighting. She really didn't want to fight a shrine maiden, but ended up enjoying herself regardless. She found a bottomless well of power deep inside her, and a chill ran up her spine. She realizes that something grave was happening in Gensokyo, even if she doesn't know how or why.
