Rank: Bet (2) → Daleth (4) / Division: Demon King Division / Familiar: Oma (Kelpie)
Second son of the prestigious Sabnock family. Refers to himself as "Onore" and others as "Nushi."
A handsome and well-rounded individual who dreams of becoming the Demon King. He is headstrong but dignified, always maintaining a haughty attitude and never bowing down to anyone, even those above him. He wears multiple metal plates around his neck like a necklace to use his family ability. He sees Iruma as his rival, but his actual rival is Alice.
His evil cycle strongly reflects his family traits, and he has only experienced it once before entering Babyls due to its dangers and his desire not to be controlled by his family's power. Although he initially refused Balam's evil cycle training, Iruma's words changed his mind, and he began training. Balam advised him to use it only in life-threatening situations. His hair turns black during his evil cycle.
At the beginning of his enrollment, he believed "power is everything" and caused trouble by attacking teacher Bruschanko and damaging part of the school building on the first day, leading to his transfer to the Misfit Class. However, after Iruma saved him from a dire situation caused by his recklessness, he expressed gratitude and apologized for his previous rudeness. Influenced by Iruma's actions, he became more thoughtful. He reconciled with Bruschanko by apologizing for his foolishness during the entrance ceremony.
During the Harvest Festival, he teamed up with Alice to defeat powerful magical beasts and gather points but ended up competing with the Dorodoro Brothers. After the competition, he continued to act with them but did not stop Alice from going to help Iruma, believing it aligned with his ambitions.
When Iruma showed interest in the Demon King, he shared various insights about it. Inspired by Iruma's words about facing things he had previously ignored, he returned home and was offered a recommendation for the TS Plan to decide the next Demon King by his uncle Baal, which he declined.
In the Heartbreaker mission, he teamed up with Ronron and Puko. During the "SOS" mission, he completed it with his comrades' help. After escaping, he encountered Atori on the second-year tower rooftop and was nearly killed by the rampaging Atori but was saved by Balam. Due to the events of the exam, he is confused by Ronron and Puko calling him "Papa."
His family magic is "Weapon Creation." He can create weapons from the same material he is biting. He can also generate new weapons from the ones he creates. When he puts his all into creating a weapon, it turns black and inflicts several times more pain on the opponent.
Sabro Sabnock is a strong and proud demon boy in "Welcome to Demon School! Iruma-kun." He dreams of becoming the next Demon King and shows off both brains and brawn. He is famous for his bold attitude, easily stands out in a crowd, and is a loyal rival to Alice Asmodeus. Despite his rough start, his kindness and willingness to change shine through, especially after being saved by Iruma Suzuki. A key part of his story is learning to grow from his past mistakes and aiming to be a great demon king in his own way.

## Plot
### First Days at Babyls

He originally believes in brute force and tries to compete fiercely with others.
### Turning Point with Iruma
During a flying test, Sabro challenges a strong beast and is nearly killed.
Iruma Suzuki saves him from danger.
Sabro thanks Iruma and apologizes for his bad behavior.
This moment changes him, making him more thoughtful and seeing Iruma as a true rival and friend.
Later, he even kneels and apologizes to his teacher, Blushenko Buer, for his wild actions at the entrance ceremony and they make peace.
### Harvest Festival and Rivalry
Sabro teams up with Alice Asmodeus during the Harvest Festival and fights powerful demon beasts to collect points.
He also competes with the Dorodoro Brothers and later joins them after the contest ends.
When Alice runs off to help Iruma, Sabro lets him go, believing that chasing his ambitions is important.
### Facing Family and Ambitions
When Iruma asks about Demon Kings, Sabro shares his knowledge and realizes he should face things he has ignored in the past.
He returns home after years and is shocked to find his uncle Baal pushing him to become a Demon King candidate through the TS Plan, which Sabro refuses.
### Heartbreaker Test
Sabro is put in a team with Ron Ron and Puko during the Heartbreaker Test (Shinzou Yaburi).
They succeed in their mission, and after going through these hardships together, Ron Ron and Puko start calling Sabro "Papa," which confuses him.
He also has a dramatic meeting with Atori on the second-floor rooftop, where he is almost killed before Shichirou Balam saves him.
### Mastering the Evil Cycle
Sabro's evil cycle is extremely strong due to his family's blood.
He usually avoids entering it, but with encouragement from Iruma, he learns to control it.
When he enters the evil cycle, his hair and weapons turn black, and the pain his weapons cause multiplies greatly.
He only uses this power in life-threatening situations or when training with Balam’s permission, because it is so dangerous.
Even a tiny cut from his black weapons can cause overwhelming pain, and the pain is shared with Sabro, but the suffering transforms into a kind of pleasure for him, so he doesn’t mind.
### Club Activities and Friendships
Sabro joins the Demon King Research Club, thinking it’s a fighting club, but stays after discovering many rare Demon King books.
He enjoys talking about Demon Kings with fellow fans and is always excited to learn more.
He often attends class events, gets along well with classmates like Clara Valac, and is popular—even more social than Alice Asmodeus.
