Crush:Nezuko

Natural Abilities:He does a quick sense of smell like Tanjiro basically,can run with super speed at his enemies, able to use fire as his dominant element and trained his thunder element from his dad.

Backstory:Long story short he was just a young little boy having just two parents and being an only child. he didn't really care about that he was used to the loneliness. So knowing at first when he was full of happiness he wanted to have friends but no one didn't like him very much and living around in the snowy grounds as well. He was full of childlike spirit just before the tragedy of his mom's passing. Now growing up he was being trained on how to kill demons by his father in secret as well helping out his neighbors from time to time, but just like Tanjiro only he was taken inside a house of an old man wanting to keep him safe inside,but unfortunately going home to find his mother dead at his feet inside the cabin making him become a true loner slowly having most of his happy mindset crumbling into pieces until finally things changed so he managed to take care and was trained on his own as another process with repressing some of his pain vowing to kill every demon in this world as he later came across Tanjiro and others at first impression reminding them of his old self but now more cold hearted and doesn't take much kindness for demons straight up kills them no mercy for none. Until meeting Nezuko helped him cope with his past and move passed the pain to no longer feel lonely and found his people. Lastly he had hoped to find his father alive which he did but as a demon and willingly chose that like Kaigaku. This made the boy feel such rage that talking was out of the question, him and Akira will fight to the death it's centered around the final battle arc. He'll receive his awakened state again once triggered.

He can rush at you at full speed starts spinning like a beyblade cut through your body with one slice or he can do an Ariel side way cut through his opponent's waist in half.

Second Form:Scorching Roar
He cuts you down with several slashes to your body, before landing one final stab through his enemy's chest, pulling his sword upward and instantly slicing their body in half and flames engulf them into ash.

Thunder breathing Third Form: Electric Dash
He can swiftly evade his enemies attacks with fast lightning speed dodges like Zenitsu. But can block them at the same time, while keeping a calm mind and can slice any body part of his choosing.

Lightning/flame breathing Fourth Form:
ThunderFlame Flash

Like Zenitsu, He can zoom through his enemies and immediately cuts off their body parts before he lands onto the ground breathes in both fire and lightning then leaps forward hitting them with a powerful cut to the chest that instantly shocks/burns them to death while putting away his sword.

Fire breathing Fifth Form: Fire Wheel
He can swings his sword in a downward spin attack cutting his enemy's whole body in half while doing a little front flip for the hell of it.

Fire breathing Sixth Form: Wrath
Alex can rush at his enemy landing five fire like slashes through their body and open wounds appear as it burns them he closes his eyes breathes in focusing on this final slash attack with a zooming past them and his sword out covered in flames at the tip then draws back his weapon with one click as sudden more cuts appears on their body then collapses and he breathes out.

Thunder breathing Seventh form: Bolt
Alex dashes forward holding out his sword at first before doing a basic vertical spin forming into this electric like ball to surround himself leaving lightning slashes on his opponent's body until they get shocked into ashes.

Tenth Form: Thunder Bullet
Similar to Zenitsu's Seventh form. Alex would charge all his power and rage into one final strike. He dashes forward at blinding speed like a bullet with his drawn out sword. This already creates a yellow Japanese shaped dragon that covers his entire body and unleashes a singular slash while doing a quick Ariel spin. Their target is instantly killed by the attack.

Eleventh Form: Dragon Sun Halo Head Dance.

Basically the same move Tanjiro used against Hantengu.

Breath style:Fire/Thunder he can also harness the power of his anger.
