Usui won the award at age 24 in 2013 (he's from Osaka). So he was born in 1989, currently 35-36 years old.

Ono won the award at age 17 in 2011 (he's from Tochigi). So he was born in 1994, currently 30-31 years old.

Now I understand why Saito is pushing Usui, maybe he feels bad because Usui started very late (start submitting manga at age 24 when normally people do it in their teens), and if he got cancelled at age 36, he might've quit manga industry altogether.
