Yagi's nosebleeds are a direct physical manifestation of his intense passion for cute children. Whenever he interacts with or is around young, adorable children, he experiences a nosebleed.
The Underlying Cause
Yagi possesses a deep affection and enthusiasm for cute children. This strong emotional response is the primary trigger for his nosebleeds. It's portrayed as an involuntary reaction to his overwhelming appreciation for their cuteness.
Unintended Consequences
Unfortunately, this unique physical reaction often leads to misinterpretations. Because he gets nosebleeds when interacting with children, Yagi frequently appears to others as if he were a pervert, despite his true intentions likely stemming from a pure, albeit overwhelming, fondness for them. This contrast between his inner passion and outward appearance creates an awkward situation for him.
