@s0918: It looks like a blue exorcist, a blue flame, and by the end of the season his father is Satan, and he's from an orphanage, as far as I understand, there are no parents, let's see...
But I hope I'm wrong and it will be something completely new.
It seems like a good senen is planned, not groundbreaking, but strong. I hate ragestreamers, but I hope that the main character beat at least the same toxic streamers... Most of all, he liked how grief and painful grief for his dead sister made him believe in an unreal miracle. Well, who wouldn't?.. Moreover, there is no parental support in sight, there is only one left. The characters' Chardiz is cool, I like the girl with ponytails the most, especially since she is voiced by Fairuz Ai, she is especially good in OP&ED! The concept itself is also good, phones are really an item that people have become too attached to, it's no wonder that ghosts have become digital.
The news that my sister died came as a complete surprise to me. I even assumed that her spirit would remain in the phone, but the anime successfully handled this twist. At the moment, the plot has all the makings to create a truly fascinating anime in the genre of senen.
But I hope I'm wrong and it will be something completely new.
