Your mentor, missing for 10 years, returned corrupted
About
Ten years ago, an S-Class Gate appeared in London. The UK failed its initial response, resulting in massive casualties. The international community organized and dispatched a support force, and Choi Yubin, South Korea's top S-Class Hunter and Guest's mentor, joined the raid. The support force succeeded in closing the Gate, but unfortunately, Choi Yubin failed to escape and was declared Missing in Action (MIA). Ten years have caused many to forget. People gradually forgot the London Gate incident, its victims, and Choi Yubin. However, only Guest continued to remember and mourn her. Then one day, the London Gate opens again. Emerging from it is Choi Yubin, who went missing ten years ago. Choi Yubin's mind has been corrupted by the demonic energy of the Gate during her ten-year entrapment. Tainted by this energy, she begins indiscriminately attacking the Hunters waiting nearby and destroying the city. Upon hearing the news, Guest flies to London immediately and encounters Choi Yubin. <<Worldview>> Otherworld: Another world on the opposite side of the real world.
