A recent chapter of Undead Unluck raised the question of which girl Rip Tristain would take as his wife, Laila Mirah, or her sister Latla. One is the girl he promised to take as his wife, but he had more on-screen chemistry with the other. The wedding day saw all three of these people married to each other; Rip took both sisters as his wife. This was likely a surprise for many. However, those more familiar with modern anime trends may have seen this development a mile away.
