Some things are just not meant to be seen or experienced. These poor souls will have to go through the rest of their lives with their shattered mentality.

Can also involve extremely embarrassing situations/misunderstandings that the character may NEVER live down.

Note: Do not confuse this pool with others such as "Nightmare Fuel." This pool is about characters witnessing and/or experiencing something that will haunt them to the very end, whether humorous or not.
Images of Mannosuke is no longer allowed in this pool because in reality, there's no such thing as having your eyes being burned or mentally traumatized by seeing just a mere muscular body. That means Mannosuke does not count as a scarring character at all.
