Tmnt one-shots

I failed you.. (Donnie au and Mikey au)

Based on demon slayer
Blood!
In this Au
Leo and Raph died when Donnie and Mikey were young
The demon that killed them was an upper moon 3
Even through his brothers were The pillars
They died within seconds
They carried their eldest brothers swords
Donatello carried Leonardo's he learned water breathing
Michanglo carried Raphaels he learned Sun breathing
Leonardo and Raphaels words were near the same
Leonardo said to Donnie
"Protect each-other no matter what.."
Raphael said to Mikey
"Keep strong.. keep breathing.."
They were the only ones who survived
Two of the Hashira came
They found both of them in a room with their dead brothers
They brought the sad news to the Hashira
They were saddened by their friends death
Donnie didn't show any emotion he stopped feeling.. after their death
Donnie hold Mikey's hand
(Like this)

Donnie promise Mikey to keep him safe

They didn't speak as much
No matter what the Hashira tried
They kept trying to learned their brothers breathing style
As they got older they were ready for final section
On every mission they went together
Never to be separated again..
Their ranks became higher and they grew stronger
With every swing
They became the Water and Flame Hashira
They swore a promise to protect each other no matter what
But that promise didn't last
When Donnie went a mission on his own
He came back to see
His brother
.
.
.
.
.
.
Dead.
.
.
His brother blood dripping from his mouth to chest
His guts ripped out
"No..No..NO.. DONT GO PLEASE! DONT LEAVE ME!" Donnie screamed
He cried his heart out.
Years passed after this
He blamed himself for his youngest brothers death
If only he took him with him
He felt like he didn't deserve to be a Hashira..
His guilt was huge..
no matter how many times they told him
"It wasn't your fault!"
Or
"Don.. no one knew it would happen"
He didn't listen
He still blamed himself
Till the day he died..
