Psyren

16 volumes

This story starts by introducing Yoshina Ageha, a high school student that seems to like helping people. Whatever problems anyone should have, he will solve them for a sum of 10,000 yen. One night, on his way home, Ageha found a ringing public phone and answered it. A red telephone card written "Psyren" on it came out of the card slot and as he took it, a strange woman voice in the phone, who seemed to know much about Ageha, asked a bunch of questions, and as he walked away with the card that will take him away to strange places.
