New season of .

An innocent young man, Ikuroo, has a parasite known as Baoh implanted in his brain by an evil organization, Doress. The parasite makes him nearly immortal and gives him the ability to transform into a really powerful beastie when he's in trouble. Doress intends to use him in some sort of ploy for financial success, world domination, or something along those lines, but when they're transporting him on a train, a young psychic girl, Sumire (who's being held by the organization due to her abilities), sets him free and the two escape together. Of course, Dr. Kasuminome is the mad scientist behind the whole Baoh thing, and he isn't about to let his test subject get away and he has considerable resources (including some superpowered lackeys, as well as a small army) at his disposal.

Tokyo-born schoolboy Yukitaka Tsutsui is moving to Yamagata Prefecture for high school on a baseball scholarship. Since he went to the top middle school in Japan for baseball, the townsfolk are very excited about his arrival. However, when he arrives in his apartment, he encounters a strange man nonchalantly reading and wearing his clothes! The stranger claims to be an alien who crash-landed on Earth and has nowhere to go. Revealing himself to be Baka Ki El Dogra, the crown prince of the planet Dogra, he is just one of the hundreds of aliens that have already made Earth their home. Despite his regal origins, the prince is an infamous intergalactic fool who thinks nothing of inconveniencing others for his own amusement. Whether he is running ridiculous tests on his subordinates, giving strange powers to random children, or just generally being a nuisance, nobody is safe from the idiot prince's antics!
