This monster seems to be a younger version of "Blue-Eyes Spirit Dragon" and can be used to Synchro Summon it, or possibly a younger version of "Blue-Eyes White Dragon" due to its lower attack and defense and its last effect, which lets you tribute this monster in order to summon "Blue-Eyes White Dragon" from your hand.
This card's Japanese name, Shirokireiryū, is derived from Shirokiryū, the name used to describe "Blue-Eyes White Dragon" from the Yu-Gi-Oh! manga.
