Chamo

MC Chamo is a radio announcer in charge of "Radio Rosa Argentina" in Buenos Aires. He reports on current major events from 8:45am to 9am, and keeps in touch with his fans on a social media site (probably Twitter) through the hashtag #ZMradio. He also talks on the phone with fans and listens to their current concerns, offering advice.

Peró Battaglia calls in after the third night from Córdoba, confessing everything about the World Devils and asking for help. Chamo is completely bewildered by everything Peró says, and tells him if he doesn't want to sleep he should drink coffee and play videogames. Peró persists, and Chamo tells him to watch some porn if he doesn't want to sleep before cutting him off to play a new hit song by Taxied. Afterwards, the meteor shower destroys the area, having been amplified by a World Devil. It is likely that Chamo was killed in the blast.

MC Chamo offers the date at the beginning of his broadcast. This gives temporal context for the story of Sekai Oni.
