A normal high school boy Kisaragi Ryuji's peaceful life is turned into an adventure by the return of his second cousin Eriko. Ryuji and Eriko seize a relic box from a black broker. In the box, they find a red dragon girl Rose. In order to protect Rose from the black organization, Ryuji decides to fight using his power as a relic handler.
Sorry about the spoiler in the synopsis, but at least that stuff happens in the first ep :P
First of, moe moe MOE XD
Rose is so damn cute, and she is voiced by Rie which has a very cute/lovely voice :D
Rose is not a tsundere, not yet at least.
Well I suck at reviewing stuff, so others will have to say more
