"Wha-What do you mean by 'Saved from the death and became the guardian of this place' ?"

Sotean asked confusingly with his eyes wide open.

Sereka smiles and said while looking towards the sky.

"Well then let me tell you what happened back there..."

*Flashback*

"Hum...I wonder what type of research I'll do with Sotean after that."

(She is wearing her school uniform.)

Then she hears a huge noise of thunderstorms outside.

"What !? Today is the sunny day then why thunderstorms !?"

"HUH !?"

Sereka responds shockingly while seeing something totally strange.

She said shockingly while looking at the big thunderstorm.
