Ketsueki (KNF)

Overview
KNF, called Ketsueki (ケツエキ/血液) in the dream world, is the main character of the fangame Nightmare Diary.

Appearance
Ketsueki is a teenage male who, in the real world, has bloodstains dotting his face, hair, scarf, pants, and shoes. Once in the dreamworld, however, the bloodstains have vanished.

Ketsueki has short green hair and blue eyes. He wears a blue jacket with slightly darker sleeves, a green scarf, orange pants and very dark green shoes.

Personality
KNF is regretful of what he's done in the past, though if wanted he could easily kill with little afterthought of his actions, despite that that's what he's so regretful of.

In the dream world, however, Ketsueki is much more calm. He's precise with his words, making sure his meaning isn't misinterpreted by anyone on accident. He's shown to be kind and willing to listen to issues.

The personality differences between the real world and the dream world are a result of KNF wanting to live as his ideal self in the dream world.

Past
KNF seems to have confined himself to his room and won't leave. Bloodstains cover KNF's room and KNF himself. It's unclear whether the blood is his own or someone elses. Not much is known about KNF's past up until this point.
