Sousei no Aquarion( 創生のアクエリオン ) on classical guitar. Credits to this guy hironou(hero knows)2525 here. He’s done many anime song on classical guitar such as hidamari sketch and full metal panic. Do check his channel on youtube.
Been working on my doujinshi, which contains self-improvised tabs for anime songs. So here’s a midi version for about half of the song that I made. Full tab in PDF format is available on his website here . In case that some newbie didn’t know, you can import your midi files to tablature editor software like guitarpro (which I highly recommends) and hopefully you get the fingerings right. Pro guitarist should have no fingering problems though.
