We Open up with you walking around New Tokyo trying to think of A Plan to stop this Akira Murderer and his General Genocide on the General Populace. Try saying that five times Fast.
Y/n: (Sigh) How am I going to stop this Man? I mean Its Magic; I don't have too Much Magic on that like other people. Maybe I could ask Strange, Or Maybe Zatanna? Hmm...
You then spotted A Woman in A JSDF Forces Suit across the Street and suddenly Ryuk appeared from behind her about ready to Push her in front of A Moving Bus but your Observation Haki Kicked in and you did something about it.
Y/n: Sticky Fingers!!
The Zipper Stand Then Unzipped your Arm and your Fist slammed into Ryuk's Face knocking him back!
Woman: KYAAAAH!
Ryuk: HE CAN SEE ME!?
Y/n: Hell Yeah, I can you Toad faced Prune! Catch the Rainbow!! (Thoughts) Thank God I can still use Made in Heaven to still steal Stands!
You then Began controlling the Rain around you as Ryuk Just smiled.
Ryuk: Huh? (Sarcastic) Ooh Rain, I'm so Scared.
He then Began being Sliced and Diced as the Shinigami Bled!
Ryuk: AAAAAAAAAAAGH!!
Y/n: Water Slicer!!
Ryuk: GOD DAMNIT!!
Ryuk then fell to the ground as you grabbed him by the collar of His Shirt!
Y/n: Ma'am Are you Okay?
Woman: Yeah...
Y/n: Do you know L?
Woman: Y-Yeah...
Y/n: Call Him for me, I think I found his Killer.
The Woman then ran off Grabbing her Phone to contact her Boss as you began Pinning Ryuk Down!
Y/n: Who the fuck are you?
Ryuk: Like I should you anything!
Y/n: (Sigh) Heavens Door!!
You then wrote down in his Mind "You shall me the Truth, only the Truth, and Nothing but the Truth".
Y/n: Now Spill the Beans?
Ryuk: Okay! Okay! My Partner is Light Yagami, He's been Killing everyone, and he's Living nearby, You can probably find his energy! It's not that Hard!
Y/n: Good. L Might want to get to him first but I have other Plans.
You then let go of Ryuk and teleported to Light's. Home.
Y/n: Hello... Light, or should I say... Akira?
Light: Ghk! H-How did you Know?
Y/n: When someone can See Shinigami it's not that Hard. Now Two Options. 1. Go to Jail, Or Die.
Light: What!? Jail!? NO! I AM A GOD OF DEATH! I WILL KILL YOU!
Y/n: Try me.
Light: MISA WRITE HIS NAME!
Misa then Began to write your name in the Death note but...
Y/n: Gum Gum Pistol!!
You then Grabbed the Death Note before Misa could do it.
Light: YOU FUCKIN IDIOT!
Light then Began to try and slap Misa but you Grabbed his arm.
Y/n: I don't Tolerate that. GER.
Light: WHAT!?
GER: MUDA! MUDAMUDAMUDAMUDAMUDAMUDAMUDAMUDAMUDAMUDAMUDAMUDAMUDAMUDAMUDAMUDAMUDAMUDAMUDAMUDAMUDAMUDAMUDAMUDAMUDAMUDAMUDAMUDAMUDAMUDAMUDAMUDAMUDAMUDAMUDAMUDAMUDAMUDAMUDAMUDAMUDAMUDAMUDAMUDAMUDAMUDAMUDAMUDAMUDAMUDAMUDAMUDAMUDAMUDAMUDAMUDAMUDAMUDAMUDAMUDAMUDAMUDAMUDAMUDAMUDAMUDAMUDAMUDAMUDAMUDAMUDAMUDA!!

Light: AAAAAAAAAAAAAAAAAAAAAAAAGH!!!
Light was then sent fly into A Wall Smashing it, as L quickly came in with A Bunch of JSDF Officers to arrest Light!
L: Is he dead?
Y/n: No. I Pumped so Many Life shots He'll Live.
L: Good, He won't escape his Crimes.
L then quickly took out Some Handcuffs and Put them on An Unconscious Light.
L: Light Yagami you are under arrest for the Crimes of Murder, Mass Murder, Criminal Cohesion, and Crimes against Humanity, you have the right to remain Silent.
You then smiled before You Turned to. Misa and she seemed really depressed, Almost Broken Really.
Y/n: (Thoughts) I need to help her. She's A Lost soul who needs Help.
You then Picked up the Death Note and Hid it Knowing it needed to be kept from the world in A Safe Place where it can never be found.
