Golden Ghost Ship ArcEdit

After Gruier requested the Serenity Royal Family's data on the Golden Ghost Ship, Yotof and bodyguard commander Catherine took one of Serenity's Corbacks and set off to deliver the data to the princess. En route, the ship was involved in combat with several other Serenity ships and was damaged when it arrived at the outskirts of the Tau Ceti system [1].

Shortly after the Bentenmaru resolved the stand-off by forcibly transmitting a message from Gruier ordering the Serenity ships to stand down, Yotof sent a message to the princess. Once the Bentenmaru had docked with the Corback, Yotof made his way to the other ship, accompanied by Catherine. After introducing himself to Marika, Yotof knelt before Gruier, saying that he was glad she was safe. He told her that nothing had happened at the royal palace while she was away. After the package was handed over, Yotof told Marika to take care of the princess before returning to the Corback, which undocked and departed [2].

Later, when Grunhilde Serenity attempted to find the Golden Ghost Ship with a fleet from the Serenity Defence Forces, Yotof was present on Queen Serendipity and received a coded message that Marika had sent to the ship. When the boarding parties from Serenity and the Bentenmaru confronted each other in the Golden Ghost Ship's bio plant, he and Catherine took off their helmets, revealing themselves to the Bentenmaru. As the princesses argued, they silently signalled to both sides to prepare for next course of action.

After the two princesses were knocked out by sleeping gas, the two parties came to a peaceful resolution. Yotof and Misa later brought the newborn child from the bio-plant to the bridge. He was by Grunhilde's side as she came to [3].

Yotof was present when Marika was awarded a medal for her help in finding the Golden Ghost Ship and bringing about a peaceful resolution [4].

Skills & AbilitiesEdit

Yotof is likely highly trained in combat skills, both armed and unarmed. According to Gruier, he is very strong. When he delivered the information on the Golden Ghost Ship to Gruier, she suspected that he and Catherine may have stolen the ship they were on, prompting Schnitzer and his men to power up their internal weaponry [2]. In the manga, he easily holds his own in a brief fight with Schnitzer [5]. He is also capable of lip-reading/talking [6].


Gruier & Grunhilde SerenityEdit

As Grand Chamberlain, Yotof is loyal to the Serenity Royal Family. He cares for the well-being of the Serenity princesses and he is willing to act without their knowledge if it would help them [3].
