Rune Factory 4 has the usual love and marriage elements of past Rune Factory/Harvest Moon games. But here's a new twist: some of the boss monsters will turn into marriage candidates once you've defeated them.
Famitsu introduces two such characters this week, the bride candidate Kohaku and the husband candidate Dilas. Kohaku starts off as a butterfly-like monster called Ambrosia. Defeat her, and she'll turn into a cute girl. She'll thank you for making her come to, and you'll take her to town to help her "recover."
(Note: Quotes were added by me. There's no hint of dirtiness in Famitsu's preview.)
As reported earlier in the day, Rune Factory 4 is due for July release on 3DS.
