Tewi is demonstrating to Reisen the specialty of 'earth' rabbits.

Also, it's 2018, and no one has commented on this doujin? Surprised me a lot.

One of my favourites
It's really cute

i want more of this pairing ^_^

canonically, tewi is probably older than reisen, actually. she's like 1600 years old at minimum iirc
