- After Meteo got the power to leave the human world, he entered heaven, the world that was entirely different from Earth. There, he could neither find any souls of the dead, nor any familiar creatures… and neither could he find his parents. The only thing Meteo could spot was a blue-haired boy, watching from a distance. Meteor, who had been waiting longingly in heaven, sensed Viz’s presence via his soul fragment (that Viz entrained). Ever since the news that Viz descended to the human world spread around heaven, Meteor had felt very regretful to know that Meteo got involved in this matter. Since then, Meteor had been quietly protecting Meteo. Now that Meteor understood the power that controlled Meteo, he hoped that, as told in heaven’s history, he would try to use Meteo’s willpower to control Viz. However, since Meteo lost his family and home, he no longer had any willpower. Viz became the only thing that Meteo could rely on to live. Knowing these facts, Viz proceeded to inhibit Meteo’s soul, leaving him with little to nothing. (credits to nameless-spy, original source can be found here).
