Yu-Gi-Oh! Zexal, Vol. 1 by Kazuki Takahashi
Yuma Tsukumo is determined to be the champion dueler. Unfortunately, he's just awful at it. During one duel, he somehow summons Astral, a "ghost dueler" only he can see. Yuma and Astral team up to win several duels.
I didn't enjoy this manga at all. I just don't *get* the Yu-Gi-Oh card duels, so this made no sense to me. I'm sure for those who play the card game, this series will be fun to read. Otherwise, just skip it. C rating.
