Kaminari watches on the news as his plan works perfectly, he contacted Daya Soun to be there to keep the footage going live. She has an ability similar to Hinode.
Everyone is watching Super verses Super wreck the city and the fight has even gotten so out of hand the riots sparked in other parts of the country.
He wanted the initial attack to occur in Kagawa first, this is the place where all Supers believe it's a safe place for them, but he will show them they are not safe anywhere, he will not give them the sense of security they are so desperately craving for.
There's footage of attacks at the Palace too, Kai was just rushed inside with Kanko, they are the only Supers in their neighbourhood, they will be dead by morning if nothing is done.
Kai doesn't even bother caring about the cameras he surfs around the building to get to Yuno's room faster. Kanko follows right behind him and Tachibana uses the front door.
