Crossed Katanas (KNY)

Note: This is an alternative story!

Tanjiro Kamado, a young boy who's family got killed by the demon king strives to take revenge and avenge his brothers, sisters and parents. Can he use the power of the sun to stop centuries of conflict?

A slightly younger Tanjiro?
Trained by Urokodaki and Rengoku?
Learning the Sun Breathing Technique at a young age?

There will be OCs in this, along with a new arc.

Kaitsuki Takasu: A young boy who's parents got killed by a demon overnight while he was gone, but doesn't resent demons. Becomes Giyuu's student after being offered to be trained by him. He is a man constantly looking for fun things to do in life to entertain himself.
Reasons for becoming a demon slayer:
99% to do something interesting in life.
1% "I mean it helps others too"

Shizuoka Tanmo: A girl who's mother is a descendant of a long line of ice breathing users. She killed her father (reasons: go read this) to save her brother from being killed by him but couldn't save her mother. She is two months older than Kaitsuki.
Can sympathize with demons on a certain level.

Reasons for becoming a slayer:
35% To stop demons from killing humans
23% Avenge her mother
41% protect her younger brother
1% To carry on the ice breathing bloodline.

Also, to give this story a "happier ending", I'll make some changes to the rules of the KNY world. (Pls don't hate me I just want a happy ending)

(I do not own any of the characters in this story unless I created my own. This is a fanfic of the original Demon slayer/Kimetsu No Yaiba)
