Live On Cardliver Kakeru

Live On Cardliver Kakaer (ライブオン CARDLIVER 翔) is a Japanese manga series written by Chouji Yoshikawa, later followed by an anime adaptation that aired from October 5, 2008 to September 27, 2009. The media are both based on the short-lived TCG "Live Battle Card: Live On".

Plot
Like so many kids his age, Kakeru is a big fan of the Live On card game. But no matter how hard he tries, he cannot break from his losing streak. Things change when one day Kakeru saves a small dog-like creature chased by weird people. The “dog” is in fact a Create Monster and gives Kakeru an unusual Live Change card, which in turn allows Kakeru to protect his newfound friend… And gets him involved in something he did not expect…
