Solivagant Vessel

Wanting to be free from everything, a boy, Yooj Sae, has been living on his own, not having any aspirations. But lately, he suddenly gets visions and dreams time after time. One day he unexpectedly gets stuck inside an invasion—unique monsters invading his school, massacring everything in their path. Escaping his first encounter, he finds out that he's been chosen by a Cryptid. Using his newly founded abilities, he decides to want to live, even if his goal is banal, if he's going to die, he'll die with a purpose. Discovering new worlds and creatures, he accepts his visions to guide his survival.

However, he didn't expect to see his fate in a vision. A single sentence.
