Quick answer

Killingham ate the Ryu Ryu no Mi, Model: Kirin (リュウリュウの実 モデル"麒麟"). It is a Mythical Zoan, named in chapter 1143.

What it does:

  • Sleep. It puts people to sleep.
  • Dreams made real. It turns what they dream into real monsters he calls MMA (ムーマ).
  • The latest use (chapter 1196). He pulls out the one thing Sanji fears most and fights alongside it.

What it does not do: keep him alive. Killingham's regeneration is the God's Knights' covenant with Imu, topped up with Imu's Omen. It is not a power of the fruit.

Evidence layers.

  • Chapters 1195–1196 are PRIMARY — MANGA VERIFIED, read directly on Shonen Jump+.
  • Earlier chapters are CHAPTER-REFERENCED: points at least two independent sources agree on.

The fruit

  • Name. Ryu Ryu no Mi, Model: Kirin — the Dragon-Dragon Fruit, in its kirin form. The kirin is the qilin of East Asian myth.
  • First seen. Killingham first appears in chapter 1140, and the fruit is named in 1143.
  • His form. He fights in a centaur-like form: a human upper body on a kirin's four-legged body.
    • 1196. Sanji calls him 「馬男」 — horse man.
    • The helmet. He fights wearing a glass bubble helmet.

Awakened? One English wiki reads it as awakened. We haven't found it stated in the chapters, so we don't claim it.

Sleep and the MMA

The core power (CHAPTER-REFERENCED):

  • Sleep. He puts people to sleep, and can do it to whole groups — Elbaf's giant children among them.
  • Dreams made real. What sleepers dream becomes real. The monsters that come out are what he calls MMA (ムーマ).

A detail from 1196 (PRIMARY). Just after using his power, Killingham shakes his head and says 「危ねェ!! 眠気が!!」 — close one, I'm getting sleepy.

That is the only hint so far that the power can pull at him too. The chapter doesn't explain it.

Chapter 1196: Dream Output, Dream-Reality, Log-Out

(PRIMARY — MANGA VERIFIED.) Chapter 1196 names three moves.

Name Reading What happens on the page
〝夢出力〟 Dream Output He pulls out "the resident of your nightmare". For Sanji, a caption names it as the thing Sanji fears: Ivankov.
〝夢現〟 Dream-Reality 「夢と現実の交差点」 — where dream and reality cross. The nightmare Ivankov and Killingham fight as one.
〝退場〟 Log-Out An attack that, with Ivankov's 「ミュールキック」, sends Sanji flying.

The readings are puns on sleep.

  • Dream Output. 夢出力 is given the reading アうとうとプット — "output" with utouto, Japanese for nodding off.
  • Log-Out. 退場 is given the reading ログアうとうと.

What Dream Output reaches for. Killingham says outright that it isn't what you'd expect: it is 深層心理, the deep psychology. Sanji is as surprised as he is — why Iva, and not Germa? Sanji's own answer is that Ivankov sees through his weakness.

How it ends, this time. Once Sanji faces what Ivankov told him, the nightmare disappears. Killingham is left asking where Sanji's "scary thing" went.

What keeps him alive

Not the fruit.

  • The covenant. Killingham is a God's Knight, and the covenant with Imu lets members regenerate.
  • Omen.
    • Chapter 1180. Imu heals him with Omen (魔気).
    • Chapter 1189. Imu hands him the Rimoshifu family spear Longinus (聖命槍), restored with Omen.
    • 1195–1196. He regenerates from every kick Sanji lands.

His own words in 1196: you only wear down, and I recover — imagine yourself five minutes from now.

What breaks it. The arc has established that wounds from attacks carrying Conqueror's Haki don't regenerate properly. Killingham says it himself in 1195–1196: Sanji can't beat a God's Knight without it. Full record: how God's Knight immortality breaks.

His record so far

  • Chapter 1177. Sanji takes him apart, and the Straw Hats tie up the pieces. (CHAPTER-REFERENCED.)
  • Chapter 1180. Imu frees him and heals him with Omen.
  • Chapters 1195–1196. He is fighting Sanji again, and undefeated. 1196 ends with Sanji on his feet, vowing not to take another hit.

What the manga hasn't said

  • Awakening. Whether the fruit is awakened.
  • The limits of Dream Output. Whether it works on anyone, or needs the target to be drowsy or hurt.
  • The sleepiness. Why Killingham himself gets sleepy.
  • Whether the fruit can be beaten, rather than Killingham himself.
