Blade Arcus from Shining

About

Blade Arcus from Shining EX is said to have a very dense story that revolves around the two protagonists, Ryuga and Pairon.

The actual combat and gameplay during battles utilizes tag-based mechanics, where a player selects a primary character as well as a secondary character. Players can only switch between the two different characters during rounds, but can also call on their partner for help using 'Link Attacks'.
