Unforeseen Simulation Joint Arc
Vlad King along with the other Yuuei teachers arrive at the USJ to help Class 1-A and All Might from the League of Villains' attack.

School Trip Arc
When Vlad King and Class B arrived at the Training Camp, Vlad King told his class that they had to extend their Quirks and that they should hurry because Class A was already there and that he wanted that his Class got the spotlight for a change. He then explained to his class that Quirks grow stronger as long as they kept on using them. Vlad King noted that this training would be done as the students developed over time but they had to do it this way because they did not have the time. He then orders his students to join Class A.

The next day Aizawa went to the facility for supplementary lessons alongside the five students that failed the test and found Vlad King who was teaching Neito Monoma there. Aizawa asked him if he could put hi students into a study exercise and Vlad did not have a problem with that since he had the same idea. Then they are all suddenly contaced by Mandalay through her Quirk and she informed them about the attack of the League of Villains. Eraserhead told Vlad to look after the students and stormed out of the building.

One day after the League of Villains' attack on the training camp, Vlad King and Shouta are questioned by Naomasa regarding the events that transpired at the training camp.

Afterwards, Vlad King along with Shouta and Mr Principal appear in Yuuei's public apology broadcast where they apologize to society for their shortcomings. However, society still criticizes Yuuei for being unable to protect the students and criticize their security measures for not ensuring the safety of the students.

Shouta tells the reporters that he decided to let the students fight due to not knowing the full situation in order to prevent the worst possible situation from happening and as a result no students were killed (which is the worst possible outcome in his opinion); Mr Principal states that the situation would have been much worse if Tetsutetsu and Itsuka did not defeat the gas masked villain. Mr Principal also says that they are seeing to the well-being of their students and have not seen any signs of emotional trauma. The reporter asks the principal if Yuuei had already failed in securing the students' well-beings due to not checking Katsuki’s mental instability and his “villain-like” performance during the Sports Festival. Vlad hopes that Shouta keeps his cool after being riled up by this particular question. Shouta answers that out of all the students, Katsuki was the one who showed that his conviction to be a Hero was the strongest and believes the villains' to be foolish if they think that they can turn Katsuki into a villain. Mr Principal backs up Shouta by saying that they are working with the Police Force to investigate Katsuki’s whereabouts and promises to retrieve him.

Quirk and Abilities
Blood Manipulation (操血) After ejecting a certain quantity of blood from the back of his glove, Vlad can freely manipulate it. With his Quirk he managed to restrain a clone of Dabi by pinning it to the wall and covering it with the blood, ending the fight in less than three seconds. When he no longer needs it, Vlad can reabsorb his blood through the same glove.

Enhanced Strength: Vlad is much stronger than the average human. He managed to lift Dabi's clone with a single hand and push it against a wall with enough power to crack it.
