(UPDATED)

Your older brother is Shu Kurenai.

And you met your brother's enemy; Lui Shirosagi.

Everyone knows the rivalry between Lui and Shu, how your brother got a scar across his eye because of that battle, and how Lui is nothing but a beyblading menace.

But somehow, you're caught up in this fued.

Lui and you bumped into each other one day, causing both of you to drop their things. You both exchanged glares, before moving on with life. However, you realised that you might have swapped phones with the White Tyrant.
