[ Brave Fire Engine Ray ] A South Korean educational animated series for preschoolers aged 4–6, Captain Rayn: Safety Hero from the Stars follows an intergalactic firefighter named Rayn and three mischievous antagonists who crash-land on Earth. After befriending a brother-sister duo, Jun and his sibling, they collaborate to tackle hazards ranging from fires and traffic risks to household dangers—cleverly delivering practical safety knowledge while fostering safety awareness and self-protection skills in young children.

Broadcast widely in South Korea and Southeast Asia, the series has become a flagship series in preschool safety education through its edutainment-driven storytelling and memorable character design. Aligned with the cognitive development of young children, it integrates critical lessons—fire safety, electrical hazard prevention, road safety—into humorous, lighthearted daily scenarios. Adopted by numerous kindergartens as supplementary teaching resources, the series demonstrates strong social utility. It maintains consistent viewership on YouTube and major Asian children’s platforms, with a merchandise line (storybooks, educational kits) and safety-themed curricula launched in select markets.

Mina : Around 5 years old, with a tender, cute loli voice. Mischievous and intensely curious, she often lands in trouble because of it. The voice actor deliberately softens the pronunciation of certain words to portray a younger girl who speaks unclearly yet is brimming with playful curiosity.

Rayne : Around 20 years old, with a righteous, warm big-brother voice. Using a serious and resolute delivery, the voice actor portrays a heroic older brother who stands firmly against wrongdoing.

Caston : A thick, typical “chubby guy” voice. The voice actor uses a lazy, foolishly endearing performance style to portray a cowardly and sluggish “alien villain.”

Peyton : A cunning, sharp, youthful voice. The voice actor frequently employs a smug, self-satisfied laugh and similar mannerisms to portray the sly, idea-filled leader of the “alien villain” group.

Sparky : A sharp, youthful voice. The voice actor often uses a clean, brisk, and detached delivery to portray the strategic mastermind among the “alien villains.”
