Here is a list of my OCs who have experienced the death of a loved one—

Kai. 
His parents where killed.

Akira.
She's Kai's brother so- ...... parents where killed.

Vex.
His wife and child where killed directly in front of him and there was nothing he could do to save them.

VK.
He killed his own sister and his parents. On purpose. With no regrets.

Killin: He had a pet bunny that died. His father threw the bunny in a fit of anger...

Mirage.
He witnessed one of his siblings committing... die- ... suicide... Another one of his sibling overdosed... And quite a few of his sibling forgot about him and left him behind.

And last but not least...

VN.
She was forced to kill her closest friend, and every new friend she made... she would be forced to kill them. She killed her own kids... Her innocence was killed...
