Toshirou

Toshi for short!

Your kalon is stuck on a deserted island! In 50 words or less, what is the one (1) item they would bring with them?

If Toshi was going to die survive on an island, then he'll bring Kyro to die survive with him. And if Kyro doesn't count, then he'll take Kyro's most prized item. Y'know, as friends do.
