 * Tae was an office worker by day and a demon slayer by night
 * The mansion was her property and it was the one she used to train and make weapons, the group's van is the one that Kotaro uses today but painted black, Kotaro's makeup is what the girls used to look beautiful, the glasses Sunshine are also her property, the shovel that Kotaro was seen in the first episode was from Tae's weapons, basically Kotaro only used what was in the mansion to make his group of idols.
 * This means that being idols is only training to fight future demons that could be released in Saga at any time.
