Log (ログ, Rogu) is a synthetic human created by Orochimaru and the older clone brother of Mitsuki.


Log was created as a synthetic human by Orochimaru, being cultivated from an embryo and given the name Mitsuki (ミツキ, Mitsuki), after "Tsuki" (, Literally meaning: Vessel) and the sixth sign of the Chinese zodiac calendar, "Mi" (, Literally meaning: Snake). However, he rebelled against Orochimaru, escaped and, now calling himself Log, started down the path of destroying the original embryo from which he originated, deeming Orochimaru's experiments to create life unethical. This background story was soon revealed to be a ruse set up by Log and Orochimaru in order to force the young Mitsuki to make a decision: either join him in destroying Orochimaru and eventually themselves, remain with Orochimaru and follow his orders, or choose his own path in life.


He seems to be a rather calm individual. He also enjoys smoking in the manga and in the uncensored version of the anime.


Log is a tall individual with dull-blue, shoulder-length hair, and golden eyes. Overall, he bears an exact resemblance to his clone sibling Mitsuki with the exception of a scar across his right cheek. When first seen, he wore a dark-coloured haori, which concealed his entire appearance. When confronting Orochimaru and Mitsuki, he wore what appeared to be a modernised form of a shinobi battle armour complete with large arm-guards, outer thigh-guards and a hybrid breastplate. He also wore a kabuki mask, which had slits for eye-holes, a protuberant nose and a frowning mouth. He takes to using an ornate snake-themed lighter, and carries a sword strapped vertically to his back. In the anime, Log wears a long hooded dark grey cloak.

Log appears to be quite skilled as he was able to temporarily fend off and counter his parent's — who himself is a renowned shinobi — attacks for a short while. He also makes use of a sword in combat, showing considerable speed and likewise skill in kenjutsu against his parent. With his Armour-Eater technique, he is able to manipulate his armour into various shapes to aid him in battle, such as encasing and restraining his opponent.

New Era

Mitsuki's Disappearance Arc

Main article: Mitsuki's Disappearance Arc In the anime, when Mitsuki apparently betrayed Konohagakure to leave with two attackers, word reached Orochimaru. He then met with Log, discussing the continued development of Mitsuki. They began to wonder what was driving Mitsuki now and if their hopes of him becoming a new light to the world would succeed.

Later, it was revealed that Mitsuki was still loyal to Konoha as he helped in stopping the attack of the Fabrications, which Log found a dull ending. Also, following the passing of Ōnoki, an investigation was done on his work about the Fabrications. However, Log soon reported that all evidence was mysteriously removed, leading him and Orochimaru to wonder who could have helped the Tsuchikage in creating such advanced artificial humans besides Orochimaru himself.

Mitsuki came to Orochimaru and Log to discuss his recent memories about Ōnoki and how they began flashing through his mind as dreams. The Sannin scanned his son's mind to research the memories with Log. There, they learned about how Mitsuki went through great personal discoveries about his being, wondering what choices are really his own and if he is on the right path. While Orochimaru was proud to see how much he was maturing into a true human being, he was concerned how the still-raw child was reacting to such personal loss. Log voiced his disapproval of erasing Mitsuki's memories after how far they had come. Ultimately, they gave Mitsuki a choice to continue enduring these painful memories or have his mind reset to before he ever even knew about Boruto. Mitsuki decided to keep his memories and move ahead.
