Just found this little cute rikuxtsurara fanart by みは.
Here's a rough translation.
1st picture - Tsurara is wearing a bikini
2nd picture - Rikuo said Reject. Too exposed. And told her to put on the haori (japanese traditional coat) XD
3rd picture - Tsurara asked Then what about this, Rikuo sama? It's an one piece~ (Rikuo sama and I are going on a trip to the sea)
4th picture - It's cute, but still reject. and put on the haori XD
