Groove announced a Touken Ranbu -Online- collaboration series earlier this year as well as the first doll as a part of the new series Isul Yagen Toushirou. Touken Ranbu -Online- is a Japanese online card game that allows the player to bring various swords to life which are all depicted as good looking boys. The game is so popular that it has gone on to inspire two diffferent anime series. The first doll in the series, Yagen Toushirou will be released in April and has a MSRP of 26000 yen which makes him one of the most expensive Groove dolls released to date but he is also one of the most elaborately detailed collaboration dolls released to date.
In addition to announcing the expansion of preorders of their new Disney collaboration Cinderella doll, Groove made a similar announcement regarding Isul Yagen Toushirou via their blog last night.  Until now Isul Yagen Toushirou had only been available for preorder via Bandai Premium’s website but now preorders have been opened via Groove’s official store as well as other Japanese retailer’s websites such as Amiami and Hobbysearch (both of which ship worldwide!). I will try to update as Yagen Toushirou becomes available for preorder via more retailers.
