Juvenile Officers

The Juvenile Officers are a group in the employ of Academia in the Yu-Gi-Oh! ARC-V anime.

Past
When students attempted to escape from Academia, the Juvenile Officers were dispatched to capture them. One student they had problems catching was Asuka Tenjōin. One day when a female student and Asuka escaped from Academia, the officers caught them and sealed the girl in a card. Before they managed to seal Asuka away, Yūshō Sakaki arrived and defeated them.

Duel Against Asuka Tenjōin
When the citizens of City thought Yuzu was fugitive from Academia, three Juvenile Officers chased her. When they cornered her, the officers were about Duel Yuzu but Asuka stepped in and commenced a Battle Royal with the trio. The three Officers all Fusion Summoned "Full Armoredog Bull Fortress" and boosted their ATK to high levels. Asuka questioned this as she activated "Machine Angel Ritual" to Ritual Summon "Cyber Angel - Vishnu", purged the field of the Juvenile Officers' Fusion Monsters with its effect, and attacked all three directly after dealing effect damage, winning the Duel.

Deck
The Juvenile Officers use "Armoredog" Decks, which focus upon Fusion Summoning their ace card, "Full Armoredog Bull Fortress". They also run large numbers of "Fusion" cards to send to the Graveyard via the effect of "Bull Fortress" in order to bolster its ATK and overwhelm the opponent through sheer force.
