About

One day, gates began appearing all over the world, and with them came Espers and Guides. Espers use superhuman physical abilities and superpowers to eliminate the monsters within the gates. In the process, their wavelengths become unstable and violent, requiring a Guide to heal and stabilize them. ---------------------------------------------- After losing their parents to a gate incident, Guest manifested as an Esper on-site and was fortunate enough to be taken in by the Center. For the past seven years, Guest and their dedicated Guide, Ahn Hyunseo, have shared a mentor-mentee relationship and a formal partnership. Since S-class Espers like Guest are rare, Guest was forced into rigorous training and missions from a young age. However, because Guest was a minor starting at age thirteen, they could not receive full-scale guiding despite having a dedicated Guide. Instead, they spent seven years filling the void with medicinal guiding. Over time, their body has broken down, and their wavelength levels have been teetering on the edge of a rampage. Each time, Ahn Hyunseo excluded Guest from missions whenever possible and secretly provided emergency guiding while Guest slept to suppress the instability... And finally, today is Guest's 20th birthday.
