Tsukuyomi

Tsukuyomi is a Shinto lunar deity that made his official debut in Seeds of Evil and is the deuteragonist in Book of Divine Beings. He is the second-born of Izanagi and Izanami, being younger than his sister Amaterasu, but older than Susano'o.

Physical Appearance
Tsukuyomi has the appearance of a handsome man with masculine features and silver-gray hair that reaches his lower back. Fitting his title as the Shinto Moon God, he dons a traditional black kimono with blue baggy pants.

Personality
Tsukuyomi comes across as a courteous and seemingly impeccable individual. However, he is known to be a sadist at times, torturing his victims and rarely, if ever, actually killing them. He is also calculating and intelligent, being able to come up with an effective strategy. Tsukuyomi has a habit of taking an interest in opponents who seem capable of squaring up against a god, the most prominent examples being Lightsen, Carlisle, and Skyjet. He also seems to often laugh at their antics (and those of their friends), as he believes that a life worth living is one that never has dull moments.

Superior Condition
Being a deity, Tsukuyomi has physical and mental abilities far surpassing that of mortals, though there are exceptions. He is able to overpower human armies with ease and can defeat other gods. Tsukuyomi is essentially one of the Shinto Royalty trio, making him more powerful than any other deity Shinto except for his sister Amaterasu.

Lunar Control
Fittingly, Tsukuyomi has the ability to manipulate the moon and all of its aspects. He has lunar energy imbued within him and can use it to bring light upon the land of mortals in the dark of night and/or to scorch the land with intense moonlight.

Combat Mastery
Tsukuyomi is a master of all forms of martial arts thanks to the training he received from his father Izanagi. He is also quite adept in swordsmanship like his mother Izanami. He is able to fight Carlisle, one of the best swordsmen in the universe and a powerful being in his own right, on equal footing. He will only use his katana, fondly named Bloody Crescent, on opponents who have proven themselves worthy.

Immortality
Tsukuyomi cannot die by natural causes or by any human means. However, he can be killed by extraordinarily powerful beings.

Superhuman Beauty
Tsukuyomi is inhumanly beautiful. He is able to seduce any woman, regardless of species (Excluding animal-type Earthlings), much to the chagrin of the other goddesses. However, his charms don't have an effect on all women.

Trivia
