About Opantsu Usagi
Opantsu Usagi was created by Kawaisouni! and has gained explosive popularity on social media. The character is known for wearing oversized panties and facing all manner of unfortunate situations with unwavering determination and innocence. This unique blend of surreal cuteness and pathos has resonated deeply with fans, earning the character the top spot in a “favorite character ranking” among teenage girls. The first comic volume published by KADOKAWA was also a major topic of conversation.
