I so want to read HoshiOta and the rest of Robo to Usakichi. Because it's about aliens and scifi. I feel like those scifi influences have reached even Blue Exorcist, with how "demons" are really beings from another dimension. The demons even lampshade that the word "demon" is just one of a gazillion names.
Robo to Usakichi also showed Kazue's penchant for including an evilside in gentle characters. The ex-convict is also hilarious.
