Floyd calls Ortho and Trey a “couple of pushovers” during the New Years event (Ortho: “…if you don’t take us seriously, I calculate your chance of losing to us as 99.8%”) and Ortho surprises Trey with his competitive streak.
When school store customers start losing interest in playing “a game they know they can’t win” Ortho observes, “so they’re the weak-willed sort who throw in the towel when they know they’ll lose.”
Trey responds, “We can’t all be as passionate about competition as you, Ortho.”
Ortho’s competitive nature comes up repeatedly during Playfulland, where he says he will be making the confident Floyd eat his words but then fails at their game. (Floyd: “Swing and a miss! That’s nine whiffs in a row.”)
Ortho finds that he is much more suited to billiards, offering to take on the entire team alone.
Later Ortho says that the best part of the game was “watching Vil, Floyd and Grim stomping their feet when they lost.”
When Grim says that he let Ortho win, Ortho says they can have a rematch and he will “wipe the floor with (Grim) again,” and that he’d like to team up against Ace and Kalim as well.
After the first students are captured and the remaining members are considering abandoning the island completely, Ortho says that there is a possibility that they will never be able to find their way back and therefore never see Jade, Lilia, Grim or the prefect again.
He then follows with, “But more to the point-that guy openly trashed us. Why would we run away without challenging him to a fight?,” saying that he would never admit defeat to Fellow. Floyd and Vil agree.
On the topic of why he joined the Master Chef class Ortho says that he only recently became interested in cooking after he heard other students talking about how the course was too difficult for beginners, which motivated him to take up the challenge.
During White Rabbit Fes Ortho intentionally plays up being a humanoid upon meeting Dylla for the first time, saying that he wanted to surprise her more than Epel did.
When a bully mocks him for his appearance before the Rabbit Run race Ortho says, “Bad guys always say stuff like that just before they lose, or weren’t you aware? Perhaps you should read up on the phenomenon,” and afterwards he upgrades his Rabbit Gear for the sole purpose of defending their title.
Grim says that he will be the anchor in order to get all the glory but Ortho says that it will be him, instead: “And next year we’ll avoid all the traps and win by a mile!”
Ortho comes up with the idea of a group investigation to try and solve the mystery of the Ramshackle dorm mirror. When Jack says he goes to sleep by 10pm Grim responds that they can just yell and shake him awake, and Ortho immediately agrees. Epel says, “Ahaha…I never knew you could be pushy, Ortho.”
Ortho also pressures Lilia for his contact information despite Lilia’s attempts to dissuade him, and encourages him to introduce his gaming friend to Idia.
