I am so confused and lost and completely thrown off. Based on the current appearance, Miku fits the brides description, but with that picture of them it's been shown that when the girls were younger they all had the same hair color. This article points to Itsuki being the bride, this discussion and the chapters points it it to Yotsuba, The child hood photo points it to being Nino, and appearance's points it Miku. Me and a lot of other people thinks he marries all five of the sisters.
Can someone and I mean anyone clear things up for me, like I will take any of the twins to be his bride but Itsuki.
