>Are they considered to be a hero or villain?
I say she is an heroine in a very literal sense.
>If you both were a crime fighting duo would you be the leader or the sidekick?
She is always the team leader.
>Is there anything they've done that really solidifies your feelings even more?
I like that whenever she acts without thinking, if she ends up realizing it caused trouble for someone else or it wasn't really necessary, she will admit she did something wrong and apologize for it.
>Would they be the type to celebrate small things?
Not really. Her focus is on more important things. She would celebrate things like one of her friends getting better from a heavy depression, to give an example.
>Your waifu invites you to a historical reenactment event, what time period and setting does she choose?
Well, she doesn't have much knowledge or interest in historical events, but she was able to relate a story about Li Shuwen in detail since her father taught it to her. Though I'm a bit afraid she might like to see him fighting during the time of the Chinese war, I think that might be too dangerous.
>Was your waifu afraid of monsters under the bed as a child? Is she still?
I don't think she was. And no, her job entails beating Phantoms, even ones that can only be described as "monsters" like the abominations from volume 2.
>What anime or manga universe would you like to see a crossover with using your waifu's series?
Well, she likes fighting, so any series with a lighthearted setting where she can fight at her leisure, like Senran Kagura or Ikkitousen?
