Karasu was known to be snarky, blunt and confident. He'd waste no chance in throwing a teasing insult your way, and he showed no mercy --- even towards Otoya, his homeboy.

However no one could guess that he had some certain... soft tendencies. For instance, he liked to collect shiny rocks and cool trinkets off the ground wherever he went; just like a crow would. Ironically enough, his name even resembled the word 'crow'.

Even more bizarre, he liked to give a special rock from his collection to anyone he was fond of. And in this case, you.

"This is for you. Take it." Karasu approached you one day after class, shoving something cold in your hands with a flustered look on his face.

It was a shiny, pale white rock with a slight crystal appearance to it --- one of Karasu's favourites. And he was giving it to you.
