the Kishin slayer (Death the kid X Reader)

you'll understand one day

after what seemed like years but was actually a few minutes kid pulled away from you and you both had tears streaming down your face "you said you'd never let go....w-why d-did you l-let go?..." kid said while looking down at the floor. a couple of his tears hit the floor, creating a tiny lake of sorrow, misery, and pain that was pent up in his soul for years now. you looked at him shocked then looked down with guilt painted all over your face "kid...i swear i didn't remember til just now that we ever met before i came to the DWMA...i never even remembered any of my past since before the age of 12 until now" you answer truthfully the question is...why didn't i remember? you thought "kid this is very important, okay? you have to help me" you say and grab kid by his shoulders "what is it? what's wrong?" kid says and looks down at you worried after what just happened...him being upset with me... he'd ignore those feelings just to help me?...but why? you thought but pushed the thought away "when did you last see me when we were younger?" you ask "it was the day after we went to the festival, i went to see you early in the morning to make plans about hanging out later that day and when i went back later you were gone" kid answers immediately. you suddenly remembered the day kid was talking about

flashback 

your dad  put some things in a vehicle of some sort and wrapped your mom up in sweaters then put her in the vehicle as well "come on sweetie" your dad said to you from the doorway as you were watching TV  "where are we going dad?" you ask as you get up and turn off the TV "were taking your mom to a doctor, okay?" he says and locks the door of the house "why do we have to take all our stuff?" you ask as you both walk to the vehicle while he held one of your little hands. before you get into the vehicle your dad stops you and kneels in front of you and places his hands on your shoulders. even though he was a reaper with a mask just like lord deaths you could still detect the worry aura running off him "you'll understand one day..." he says in the sweetest voice a reaper like himself could manage then gives you a kiss on your forehead. as the memory fades all you hear and remember is your mother having a strange maniac like laughing fit going on and your dads words echoing in your mind "you'll understand one day..." 

end of flashback 

"you'll understand one day..." you say without realizing it "what?" kid asks and you snap out of your thoughts "that's what he meant that day!" you say finally understanding what your fathers words meant all those years ago "what are you talking about?" kid asks "that day after the festival, my dad he told me something and now i finally understand why we left...why i left you..." you say and look down with the pain of guilt growing just a little bigger in your chest "what did he tell you?" kid asks curiously "he told me, you'll understand one day. kid we left because my mom was going crazy and my dad didn't think she could take it much longer and he didn't want to risk his best friends city, your father's city, from having her destruction" you say finally figuring out why you left kid so many years ago "he did one small act to keep a bigger act that could've destroyed our home forever" kid says. it was silent for a couple seconds "i always thought your dad was wise and noble" kid says "i always did too..." you say and look over at a small framed picture of you and your dad when you were 3 you were brave...i miss you daddy you thought. you yawned and kid did too "hey its been an emotional night, why don't we go to bed...you can sleep here for tonight" you say to kid then head up stairs to take a shower then sleep.
