The first character to be depicted in the Getsuyoubi no Tawawa series. On the series' seventh anniversary, she was featured for the first time since her debut and christened as the "Originator" (始祖 shiso).
Also nicknamed the "Founding 〇〇〇an" (始祖の巨〇), a pun on the name of the Founding Titan from Shingeki no Kyojin (始祖の巨人), as the omission of the last word's second kanji leaves it open for reinterpretation as kyonyuu (巨乳, "huge breasts"), referring to Getsuyoubi no Tawawa's basic premise of revolving around female characters with breasts that are large at their smallest. Incidentally, the pun also works in English, as the "tit" in "titan" is slang for a woman's breast.
