secret villain
maybe?
She's probably obsessed with Iris and got jealous when she found out Iris had been taking private lessons from Alta. That's why when Alta agreed to take her in, she focused more on her sharing a secret with Iris than getting to study more advanced lessons on swordsmanship.
*whispers* thats what they want us to believe
True, hahaha
My other guess is she's an orphan adopted into Iris' noble household and was taught to be a ninja companion for the oujo-sama lol
Nope she's just super obsessed. Well technically, you're half right. She IS an assassin. However it's the Sword Saint's Enemies that she assassinates. She's the Sword Saint's bodyguard. Otherwise the Sword Saint would be long dead.
1) she literally stalked her friend for a whole week? She cant stand not being involved with everything that girl does. Uhm. It feels like she could be one of the assassins
Maybe she intentionally isolates her too
2)she's more skilled than the princess- but no one acknowledges it- she downplays it, she intentionally wants to be seen as a background- she's hiding. Isn't she as skilled as the assassins? Hmmm
3) she kind of antagonizes the mc
