For the last addition to my harem, I take Wanko, formally known as Kawakami Kazuko, from Maji de Watashi ni Koishinasai! as my waifu!
I only recently played Majikoi, and it took me completely by surprise. I didn't play Wanko's route until the end but it took me completely off guard. A carefree girl but fully applies herself to meet her goals. I love this girl.
