E's Otherwise Kai Kudo is a powerful psychic. People would describe him as an Esper or E, though he doesn't seem to know it. Following his sister Hikaru who is gravely ill to an organization called Ashurum that promises to make her well, Kai is recruited by Eiji into another branch of Ashurum called Aeses where he undergoes exstensive military and psychic training. A year later, on his second mission out to stop the guerilla army in Gald City from using psychics, Kai and another Aeses student, Shenron Belvedere, fight each other and Kai ends up hurt. He washes up ashore outside Gald City and isrescued by Aska and her brother Yuki.

Once awake, Kai decides to view Ashurum from the outside to see what is really going on.

My Thoughts
E's Otherwise is really good. It follows Kai's life as he discovers who he is, and how strong he can be psychic-wise. There are side plots that offer intrigue but that is focused on Kai as well. It's a series I highly recommend you watch if you are interested in characters that can use their minds to levitate things, that can appear and disappear at will, if you do like this stuff, you won't be disappointed.
