Usada Pekora is a Japanese virtual YouTuber with Hololive, a rabbit-themed streamer known for her playful, mischievous persona and loyal fanbase. Otsupeko deshita is her familiar closing phrase, a Pekora-flavoured way of thanking viewers at the end of a broadcast. Fan clips and edits have carried the farewell beyond her own streams, turning it into a recognisable sign-off for Pekora content online. Its continued use comes from that strong association: hearing it instantly signals the end of a Pekora moment.
