Long time ago, there was a girls named Kagura and Hanabi.

They have a strongest friendship after all , the same thing to their mothers but they are a little bit different.

Kagura masters or learns how to use Umbrella with the control of YinYang

while Hanabi learns their clan skill signature and also "Higanbana" or the skill that she created. Her grandpa was shocked because she is the first person to create own skill without any help of elders, but months ago, Hanabi confirms that skill and gets blessed by the clan leaders and Buddhas.

Kagura loves her choice to use umbrella forever same thing on Hanabi but something's fishy...

Hanabi was jealous of Kagura since they were child.

It is because Kagura "Gets what's she don't and she want" always .

Hanabi was just a normal little girl watching her older cousin and her big brother on training which make her influenced.

Hanabi was weak and unappealing unlike Kagura.

Kagura was always on people's eyes, one more missing was both of Hana's parents...

So Hanabi always stays on Kagura's back if they are together. Kagura loves Hanabi so much until they get on their new university.
