ラブひな～愛は言葉の中に～

This adventure game's main focus is on collecting words for one of the five heroines from the series. You are Keitarou Urashima, the protagonist from the series, living together in a huge mansion with Naru Narusegawa, Shinobu Maehara, Kaolla Su, Motoko Aoyama, and Mitsune Konno. You can go to any one of their rooms and check the words you have unlocked for each of the characters, and by combining them start the event scenes which are similar to a visual novel in style with full voice-acting, for player character included.
