Chun Chun Maru is spoken by Megumin, the explosion-obsessed mage from KonoSuba, voiced by Rie Takahashi. The phrase became a favourite line among fans of the series, who clipped it, shared it in anime meme edits, and reused it as a reaction sound across short-form video and soundboards. Its appeal is partly the contrast between Megumin's serious magical ambitions and the sweet, sing-song way she says it. That combination keeps it popular for lighthearted edits long after viewers first hear it.
