Humans

Humans, or scientifically known as homo sapiens, are, now along with monsters once more, the dominant species on Earth, They are known for their DETERMINATION and were responsible for igniting the Human-Monster war and trapping Monsters underground with a BARRIER. Along with monsters, humans rule over the Earth.

DETERMINATION
Most, if not all, humans have a lot of DETERMINATION (DT). However, those with the DETERMINATION SOUL trait or high LV has significantly more. DETERMINATION can be extracted from human SOULs. Monsters react very negatively to DETERMINATION; they end up melting and in some cases may be lethal, though it can bring a monster back from 'falling down' at the cost of their body melting. An exception is in Undyne, as she has small traces of DT, but shows no negative side effects. In fact, she is stronger and more determined than the average monster.
