Gregorio Valentino

He is the Barista at Rokuhōdō. He grew up and learned his trade in Italy. He was an 'angry young man' as a teenager, but after he was taken in by a Barista there, he learnt the art from him which also changed his character. This is also the reason he has a lever operated espresso machine at Rokuhōdō. He returned to Japan since it was his father's country. Although his coffee is extremely delicious, he is totally clueless about his iffy latte art. He is cheerful and outgoing. He is also a member of the local duck boating club. He often has friendly arguments with Tsubaki.
