This kit is the Xeno Alma Hydro Zeeforce, released as part of Kotobukiya's Arcarnadia series. This time around it's not a girl-pla — it's a seahorse-type character. Arcarnadia Velrettacan be combined with it as additional armaments.

The main body itself takes the form of a classic seahorse, with detailing and a silhouette that looks like it's straight out of mythology. Posability is limited due to the restricted range of motion, but the joints are solid so it holds poses well. You can also detach Sword A and Sword B from the wings, unfold their handles, and use them as weapons for other kits — and with the separate joint parts, you can display both swords together on a stand.

Disassemble the main body and you can apply the pieces to Velretta as right shoulder and left thigh armor, a backpack, and additional weapons — and being dedicated armaments, they fit together naturally without any issues. All in all, this is a kit with a unique seahorse concept where the design itself is its biggest selling point. If the style appeals to you, or if you already own Velretta, this seems like a fun little kit to pick up and enjoy. :-)
