i started watching this because i was curious of how a puzzle anime would be like... and it blew my mind away! already the first episode was beyond epic and keept me wanting more but for every episode it gets better and better and it did not take long for me to actually think of it as the best anime i had ever seen. The characters are awesome and have their own story that makes you love them espacially Kaito and Rook. The Storyline keeps you on the edge of your seat at many points throughout the show and the "puzzle fights" are to epic to find the right word for! The soundtrack by Akio Izutzu is amazing and have so much emotion in it! Phi-Brain starts out as a action/comedy anime but it grows into one of the deepest stories i ever seen and it made me get tears in my eyes a lot after about 13 episodes. It's new but still very underrated and should be watched by many more because it's that amazing definatly better then the other anime's that get attention this year like Mirai Nikki and Guilty Crown! So if you want epic fights,amazing storyline,awesome characters,wonderful music and a bit of comedy here and there Phi-Brain is the anime for you! Hope more will watch it since it definatly deserves attention! (show less)
