Super Black Jack Scans
The anime is known as Rio Rainbow Gate. The story had potential but it fell flat from episode to episode. The "gate" battles (card battles, there are 13 gates) could have been designed better, something more Yugioh-ish would have been nice. The characters were mediocre but the character design was very nice.
theme about gamble. i think this is first in many ways. but then it's not really about gambling. too untrue in how characters play games. apart from main character, other characters seem very little use for story. at least should have more insights about the two main characters' growing up, showing us their relationships in a bitter-love bonds. wanted to see more development in characters.that gamble society police samuri is really cute.
