Luke was dodging every hit from the demon since giving he was small and was moving incredibly fast.
He then was knocked down and then quickly got up running from the demon who followed him.
During this Simeon tried getting up to follow them untill Lucifer and Tanjiro walked and asked while helping him.
Lucifer: what happened!?"
Simeon : I....I got hurt and Luke came out.... he's fighting the demon..... he's going to get hurt...."
Tanjiro : Lucifer you stay here with him I'll go help Luke.
Tanjiro: i-!?
Suddenly they heard a loud crash in the distance and an explosion and smoke in the air and Tanjiro took off towards it.
Once he got to where it came from he saw the demon and then saw a home on fire destroy and in rubble and didn't see Luke anywhere and feared the worse.
Until suddenly something start standing up from the rubble.
And to Tanjiro's surprised it was Luke but he looked bigger like an adult like nezuko's other form.
And his eyes were as blue as a blue moon and full of anger and power that could strike fear in anything.
His wings then opened up and the pure force from that caused the fire to blow out.
And with that he immediately charged at the demon.
And in that split second the demon had no time to fight back as Luke's claw Like hand touched his face knocking his head right off his body and throwing it.
Tanjiro : Luke?"
Luke then turned his head towards him and started walking towards him until he heard one of the brothers in trouble and quickly took off.
And Tanjiro followed closed behind.
Meanwhile everyone was together except for a few others seeming to get surrounded by the demons.
Mammon : ok they weren't lying!"
Levi : there's clearly too many for us!"
Beel then looked around and asked worried.
Beel : where's MC!?"
Everyone quickly looked
Around and saw MC on the ground in the distance trying to figure a demon off them.
And in that split second Luke showed up and kicked the Demon's head clean off.
And everyone froze in horror not believing what they just saw.
But MC then quickly got up and said seeing luke looking Different.
MC : they do grow up fast I guess....."
Luke looked at them but quickly looked away and started going after the other demons.
And MC then ran to everyone and watch with everyone as Luke was fighting the demons showing no mercy in what he was doing.
And seemed to be getting carried away with it letting the demon side take full control. But he was killing the demons so it was good.
Soon Tanjiro got there meeting up with Lucifer and Simeon and they all saw what Luke was doing.
Tanjiro : in this form he could lose control we need to be careful"
Mammon : how can he do that!?"
Tanjiro : he must of been given too much blood.....from ....."
Simeon : from who?
Tanjiro : Muzan. The king of demons here who also turned my sister into one. Luke has the same power as a upper moon demon which are the worse under Muzan"
Lucifer : .....i-!?
Suddenly everyone froze in horror as they saw the demon slice Luke head off and throw it out of sight.
Luke's body then started walking back stumbleing and falling to it's knees.
But before it could fall over suddenly someone in the distance kicked it back and it landed right back on his body.
He then stood up as the scar healed and he started laughing and growling which scared the demons.
Then Nezuko showed up who was also in her bigger form and they immediately started fighting the demons as they were running off scared.
Few minutes later everyone tried finding Nexuko and Luke as they splitted off going after demons.
Some of the brothers and Simeon found Luke holding a demon by the neck and dragging him towards an open field as the sun was rising.
And everyone started panicking until Luke held the demon up by the sun and then covered himself with his wings and started to watch as the demon started burning alive by the sunlight.
And Luke was laughing enjoying this until Simeon snap him out of it.
Simeon : LUKE THAT'S ENOUGH STOP!"
Luke didn't stop not until the demon died.
Simeon: Luke! Don't lose control like that again please!"
Luke was about to do something until everyone heard Nezuko screaming and Luke immediately took off and everyone followed him.
Luke saw Nezuko on the ground burning up and quickly ran towards her and fell to his knees using his wings and body to shield her from the sun by her started burning up himself.
Then everyone showed up
