I don't even think it's "she likes fighting", more so she likes when there's an equal fight. She's pretty much polite until someone goes first or starts a fight, and she loves irritating them, not necessarily aggressing.
-Human friendship level: Very poor
-if anyone disturbs her, be they youkai or human, she eliminates them no matter what
-She doesn't feel an atom of fear when fighting humans or youkai, and loves rubbing people the wrong way.
-This class of youkai is not interested in the average human, and only pays attention to equally strong youkai or humans with special abilities.
-She gives proper greetings
-The stronger the youkai, the more polite they normally are.
-Luckily, she isn't interested in boring battles, so as long as you don't attack, set up a trap, or set her flower field on fire, you should be fine.
Eh, the controversy to this is probably how it came along anyways.
