Kingdom Hearts vol.1 by Shiro Amano is made like a regular left to right book. But it's still manga. The manga is simply entertaining. Although it sticks to what the storyline is all about, he adds comedy in the mix. Its an adaption, so the story isn't exactly exactly like the gameplay. But, it has all of the concept. In the beginning, you may be thinking "This looks like a bit altared face" (Source from my friends reaction) but his artwork looks a bit different in vol.2. Amano-san also adds extras at the end. For vol.1, he shows his ORIGINAL artwork before he started off. You can see how he wrote little notes besides some of it to show his opinions and its so original. People may be like "Big deal...original artwork" but its still important. See how different it could've been or see how good this person is and even if he sold out his original artwork, its a collectors piece. So, the book has orginal concept,comedic action, and extras. Filling 100+ pages. What more? This book got a 5/5!!
