Umi no Sakyuugi Nocturne

[Fuyu Maiden]

Alright, while trying to find any raws for Shinshi Doumei Cross chapter 41 on the internet I stumbled onto a Baka-Updates page for a work that is listed as Arina Tanemura's but seems to have almost no information.

Umi no Sakyuugi Nocturne

I mean...the image definitely looks like Arina's artwork, but is it just a one-shot or something? It sort of seems that way since it's listed as being serialized in Ribon Special instead of just Ribon like Shinshi Doumei Cross. Even if it's just a One-Shot, I want to know about it. So if anyone knows anything please share it.

It's definitely Arina Tanumra's work and I think it's a one-shot. I don't know anything more than that.

It's Arina-chi's work, alright. I think it's a side story. Her current series is.... Shinshi Doumei Cross.
