Well, it is indeed Emiri Imanaka of Abaranger once transformed into Abarepink, although with that special pig mask (episode 11 of Abaranger).... Now the Gokaiger episode 29 put in more details into the obsession and, now, Emiri Sanjou (married to Yukito) give GokaiPink a AbarePink ranger key. Emiri was played by actress Michi Nishijima. Well, that's about Gokaiger episode 29 for Abaranger theme. A funny episode and also highlighted is Ahim cosplay into school teenage and nurse... hmm talk about obsession.
Now the next half show of Gokaiger will be interesting as always.
