3rd intro: Ichirin no Hana --> Awesome song with a great animation video. D-Tecnolife almost made this spot though.
3rd ending: Houki Boshi --> I just love this song! It's just.... so good, and the instrumental version is just as good. Plus, they made 13 different endings with this song [img]i/expressions/face-icon-small-smile.gif[/img]
