Mana Walker

Mana Walker is the adoptive father of Allen Walker, and the older brother of the 14th Noah.

Appearance
Mana's face is obscured during the series, so it is difficult to see his face.

Personality
Mana seems to be quite a kind person, as he adopted Allen, who was abandoned by his biological parents for his deformed left arm when Allen was just an Infant. This shows that Mana has no prejudice against such things. Before his exorcism, Mana told Allen that he loved him.

However, after the death of the 14th Noah and prior to his own, Mana was acting somewhat strange, as though he was losing it. Allen then was hit by the conflict of whether Mana truly loved him or just his brother, who was reincarnated within Allen.

History
He dies not long after he meets up with and travels with Allen after forming a father/son-like relationship. Allen then calls upon the Earl, with promises to bring Mana back to life, Allen accepts and brings him back. The Earl commands the newly revived Mana to kill Allen, but his left arm activates for the first time and kills Mana's Akuma on its own accord after Mana saying he loves Allen causing Allen's hair to turn white from shock. Mana and Allen together created new symbols for music scores years ago. The symbols were used in the piano song that Allen played to save the Noah's Ark. The melody is inside Timcampy. "Soshite bouya ha nemuri ni tsuite. Ikizuku hai no naka no honou. Hitotsu, futatsu to. Ukabu fukurami itoshii yokogao. Daichi ni taruru ikusen no yume, yume. Gin no hitomi ni yuragu yoru ni. Umare ochita kagayaku omae iku oku no toshitsuki ga. Ikutsu inori wo tsuchi e kaeshitemo. Watashi ha inori tsuzukeru. Douka kono ko ni ai wo. Tsuinaida te ni kisu wo."

- The song in Japanese.

"And then the boy falls asleep. The flame inside the breathing ashes. One, then two. The floating swelling, the dear profile. Thousands of dreams, dreams, that pour onto the earth. On the night when the silver eyes swings. The shining you, who was born. No matter how many millions of years, return the prayers to Earth. I continue praying. Love for the last. Kiss for the joined hands."

- The song translated into English.
