Kaguya probably wants to use the computer and tells Eirin to let her use it or she'll kill herself. Of course Eirin ignores Kaguya's hissy fit and pointless threats, so the spoiled princess goes to kill herself, but is too much of a wimp to go through with it. No idea why Kaguya vomits, maybe she has an eating disorder.
Is there any tag for hourai elixir? EDIT : Or maybe hourai_elixir( liquid) ?
