Mitsuhanii

Mitsu, our resident tea witch. She knows a lot about tea and brewing, and even has her own nerdy, themed tea store (available online!), the Black Lotus. (Yes, this is a Magic the Gathering reference. I told you it was nerdy. Check it out! If not to buy something, then to understand the level of nerdiness and creativity.)

She also makes cakes! I don't think those are available online however. Harder to ship them without ruining them.

May or may not be a paladin of Riku's rival deitea. Either way, that doesn't stop them from being friends.
