Saechika Hachiouji

He is Rui's little brother and a Code:Name. It was assume he died in the accident years ago, but Code: Emperor revealed he is still alive. In chapter 94, he is reveal to be Code: Closer and in 95 revealed to be Rui's little brother. He has the same powers as his sister, but is more powerful. His shadows is capable of "eating" powers.

It is comfirmed in Chapter 96 that Saechika is more powerful than Rui, since he has two different powers, just like Code:Seeker, Oogami's brother. It is still a mystery of his second power, however it is hinted that he too has a side effect like Rui when he overuses his powers(when she uses empress pandora). It would seems that Saechika always knew Rui was his sister and wanted see her, however Code:names are unable to reveal themselves to Code:Breakers. He was saved by Heike during the fight.
