yoru decided that ikuto was already free from easter and had his freedom and ikuto gave birth to yoru when he was a kid because he was dragged into the whole embryo thing so he Lost his freedom to easter and at the end of the series he gets his freedom with the embryo being that boys hearts egg and all anywhoo ran miki and su decided amu got her `who she wanted to be` consept down so they were sent into shugo chara utoto which is where the shugo chara go after their possesers have gotten their dream au consrpts from the help of their chara so dia knew of this and amu and dia went into the utoto in tafuta of the three and they meet yoru on the way and he explanes what happened to him so they go to ikuto in paris au england wherever he was and yoru explaines to ikuto that he dosent need him now while amu hid behind a building and then yoru returned into ikutos hearts egg ( i was almost about to cry when that happened cuzz ill miss yoru and ikuto wounlt be a kitty cat) then amu says something and ikuto heard her and he alisema something about how he loved her then she blushed then she went back into the utoto and found miki suu and rans sparks which she needed to get them back then she got out of the utoto and she was holding miki su and rans eggs and i have no idea what happened after that and she also meets the king and i didnt want to spoil the suprise of what readers find out so get the manga its good i cried for the yoru part cuzz im an amuto shabiki and if feels like yoru is like ikutos brother au something like that so it was sad but the other stuff was cool
