And here's another semblance of my OC, Zena Oyuki Bloodheart. I think this semblance verges on being OP, so please share your thoughts.
“So, what is wrong with her aura?”
“I don’t know. But her aura doesn’t have any of those healing abilities we have. She can’t use it to boost her physical strength or even to protect herself, either. She only can use it to fuel her semblance.”
“That’s pretty hard to swallow.”
“It is. But data readings tell me something else.”
“What is it?”
“This is not her original semblance.”
“I think her semblance was changed….most likely the previous semblance was the same in nature as this one, but now only far more….perverted than the first. I don’t know what the heck “they” did to her, but…..”
“...I’m sure that it is not what anyone should do to anyone.”

This complicated, yet powerful semblance is similar to the Rejin’s semblance, Awakening, on the grounds that they both have “evolved” under harsh (in Zena’s case, inhumane) conditions. While this semblance’s influence is out of the league, its cost is hefty also.
This semblance is actually an Hallucination semblance (just like Emerald Sustri) but due to the training and body/aura modification of inhumane level, this semblance was mutated into one separate semblance with the similar, but more stronger effects.
Hijack allows the user to “hijack” people’s perception of their senses (hearing, sight, touch, smell, and even taste) and their actions, and mold them to the user’s own liking for a short period of time, usually about 4 to 5 seconds. User is allowed to hijack more than one sense at a time, depending on their mastery of the semblance. They may also hijack actions and senses at the same time, but this is taxing to the user’s body, and its duration becomes shorter, usually about 1 to 2 seconds. User has to be around within 6m range of the victim to execute this semblance. And most of all, this may influence up to 10 people at the same time, without any detrimental effects on the user.
What makes this semblance truly terrifying about this semblance is that when used with senses+action hijacking, it is possible to make it so that victim will not realize she is using this semblance on you. When she is hijacking your actions, user can control your perspective will edit yourself into thinking that what you are doing is natural.
Extra A swings his sword toward the user.
User activates semblance, hijacking the A’s actions to drop the sword, and influencing A’s sight, hearing, and touch to make him believe that he is actually swinging his sword toward her.
A believes that he is swinging his sword, but in reality, he dropped it, and his body is frozen in the mid-swinging motion.
Let's go make a grave for poor Extra A.
This semblance, however, comes with heavy prices to the user. First off, this semblance was artificially modified by Oyuki clan, which includes extreme modification of aura and body, which forces user to use all her aura to fuel her semblance, nothing else. This makes the user extremely vulnerable to the direct hits. Naturally, the other applications of the aura are disabled, including its simple defense mechanism. The users also suffer from constant, lifelong, and harsh headaches, even if user is not using the semblance, which is detrimental to the life of the user as a living being. Users will suffer more intense headaches when actually using semblance.
In conclusion, the user of this semblance need to be the master of deceptions and trickery, and also master of close combat. Because of this semblance, user needs to have some kind of backup plan for the absence of aura defense. Also, user has to be aware of the fact that actions requiring the usage of aura (for example, unlocking of someone's aura) cannot be performed in anyway.
