Chun Chun Maru is the name Kazuma gives his sword in KonoSuba, the fantasy comedy anime centred on Kazuma and his party, including the explosion mage Megumin, voiced by Rie Takahashi. Fans picked up on the name because it sounds both cute and oddly grand for a weapon, and short voice clips of Megumin explaining it began circulating in anime edits and on soundboards. It still works today because it instantly signals Konosuba humour, dramatic naming and Megumin's enthusiastic delivery in just a few seconds.
