What? A twist in the reincarnation that at least makes some use of prior life abilities? Truly a rarity. It's also cute enough in its own way, with a relatively competent prince and reasonable enough high level plot. On the whole, this is a solid story that uses its setup fairly well.
My ratings on the series, from best to worst:
1-2, 2-3, 2-4, 4-5, 5-2, 6-1, 2-2, 4-1, 5-5, 2-1, 1-4, 3-2, 4-4, 4-3, 4-2, 3-1, 5-1, 4-6, 2-6, 5-4, 1-5, 3-3, 3-4, 1-3, 2-5, 3-5, 5-3, 1-1
