The lunar god in Shintoism. He was born of Izanagi's right eye as he bathed after his descent to the underworld, thus making him the brother of Amaterasu and Susano-O.
"Soul of the light of heaven and earth, light of the moon, come here to me, Tsukuyomi!"
—Tsukuyomi
Special Forces Agent Narukawa is the reincarnation of Tsukuyomi, and as such, shows a familiarity that he cannot define with Akemi Nakajima, the reincarnation of Izanagi. When Nakajima is tormented by Isma Feed and Set through their torture of Yumiko Shirasagi, Tsukuyomi reawakens within Narukawa. Tsukuyomi quickly dispatches Isma and Typhon with arrows of light and commands that Charles Feed takes Nakajima to safety, identifying Nakajima as a important warrior. Tsukuyomi attempts to hold off Set as they escape, and is killed by the demon.
Persona 4 Arena Ultimax
Known as Tsukiyomi, it is the Persona of Sho Minazuki when he surfaces through a Plume of Dusk, and is, befittingly, of the Moon Arcana. During Sho's Instant Kill attack Tsukiyomi's body is changed by the black substance attacking the opponent, replacing his white lines with red ones similar to Magatsu-Izanagi. His sword also resembles a scythe as it cuts through the opponent, disintegrating them. In the True Ending Minazuki disappears and Sho inherits Tsukiyomi from the plume.
Its only skills so far from the SMT series are both the Life Drain and Spirit Drain, used as command throws. It can also combine both versions into one through a Skill Boost (since both moves share the same motion but end in different buttons for their input/command).
Persona x Detective Naoto
Tsukuyomi appears as the Persona of Sousei Kurogami. According to Tetsuma Tsuge, Sousei awakened Tsukuyomi not long after Aigis had successfully awakened Palladion, but unlike the latter, Tsukuyomi has no combat ability at all, thus causing Sousei to be classified as a failure. Much like Amatsu Mikaboshi, Tsukuyomi is unable to engage in combat, but makes up for this flaw with a very special ability: Past Reading. This special skill enables Tsukuyomi to hear the thoughts of deceased people up to six months after their deaths. However, if Amatsu Mikaboshi synchronizes with Tsukuyomi, this duration can be extended to three years.
