Mutsuo Hoshino is the eldest son of the Hoshino family and the son of Tomino Hoshino and Mizue Hoshino and brother to Michiru Hoshino, introduced in Katamari Damacy who has appeared in all subsequent main series games. He tries to point out the obvious to his parents like noticing the stars vanishing on TV and appearances of The King in the distance. His description on Katamari on the Web reads: "The eldest son of the Hoshino family. He is a normal elementary school student. His favorite subject is morality."[1]
In Katamari Damacy, he appears in the cutscenes along with his sister Michiru and their parents. He has a keen eye for noticing a lot of things, but is often ignored as the stuff he says or tries to point out "just don't happen."
In We ♥ Katamari, he's a fan that's in the Select Meadow and he gives out the Cousins Stage. He says that Katamari Damacy is a lot of fun and states that in We ♥ Katamari there's a lot more cousins and that there's 40 of them including The Prince, it's not like that needed an upgrade. He tells us that there are so many that he had forgotten all their names and that he has no choice but to remember by making friends with them all and requests to roll up all the cousins. He can be seen in some of the levels although not able to be rolled up in these levels.
