On top of the 6 Blu-ray and DVD volumes that will pack the ongoing TV anime series Amagami SS Plus, which have already been known to include unaired anime shorts, there will also be a 7th volume. One that will bring a whole new OVA episode, taking place at a hot spring (hence its title “Onsen”), and focusing on Miya Tachibana (pictured below).

Amagami SS - Miya Tachibana

Miya already had another OVA episode dedicated to her last year, as the culmnation of the first Amagami SS season’s Blu-ray / DVD releases. She is the younger sister of protagonist Junichi, and keeps calling him “nii-nii”. And to make sure you won’t forget about her anytime soon, a new Miya Tachibana gallery now welcomes you locally.

More info about the 7th volume’s contents and the OVA’s story, by AnimeNewsNetwork:

“The story is set on a Sunday as Christmas draws near and the male lead Jun’ichi has not made any moves on a girl. Jun’ichi’s sister Miya goes to a hot spring that just opened with her classmates Sae and Ai. However, the other Amagami heroines – Tsukasa, Rihoko, Kaoru, and Haruka – also appear there. Without Jun’ichi, the girls talk among themselves at the hot spring.”
