Right. I'm back.
Here is a semblance, that depends on the user to be either very practical or out of the league OP.
If you ever played an RPG games before, you would notice that any tools or items that you acquire puts themselves into the special place called Inventory, or Item Box.
This semblance is basically like that, but little bit more complicated.
The semblance is basically composed of one "garage", "in-put" portal, and "out-put" portal.
"Garage" itself is a space that only the user can use, a completely different "mini dimension" where user can store any non-living things, from weapons to consumables and even veichles, just like the notion of the Item Box. The garage itself is what we would call rectangular shape. The limits of how much the user can store inside the garage varies from user to user, and largely depends on their training and usage of the semblance. It is known that time flows normally in that space.
"In-put" portal is basically portal that user opens when they want to put things in. The portal "sucks in" the object and stores it in the garage. Of course, "out-put" portal is for taking out the things that user needs right now. Important thing to note is that this portals can be summoned anywhere at anytime within 2m dome shaped radius centering around the user. For example, you may open the in-put portal to put the pencil 1.3m away from you in the garage. Same goes with output portal. The radius that you may open the portal could increase via training and frequent usage. It is interesting to note that in-put and out-put portal may be opened at the same time.
Garage itself can take in living organisms, but not for too long. It will forcefully "spit out" the living organism when it is in the garage for too long. It is very taxing to the user to keep living beings inside the garage, and leads to serious case of aura depletion. It is VERY interesting thing to know that even user themselves may go inside the garage, even though it is extremely dangerous. It is possible to put only the part of the living organism in without any consequences.
This semblance is constantly active, and cannot be deactivated unless the user is dead. Of course, you would need to use some amount of aura in order to put stuff in and out of the garage. Bigger the object you take in or out, more aura you will use up.
Pretty bland semblance, no? It just basically let you pack bigger bag packs without worrying about them getting in your way, or even store back up weapons just in case. Very useful in practical applications, both in daily lives and battles.
Of course, that's about it when you are only using it for those kind of applications.
If the user have masterful control over this semblance, this semblance can be utilized in very offensive way.
Let's start with most obvious thing: if your enemy is within your portal radius, you may drop heavy things on them by creating out-putting portal over their head. Imagine a big Roadroller just dropping out of no where on top of your enemies' head.
User may open in-put and out-put portal at the same time, and they may put in part of themselves without any consequences. This may create some serious long range attack ability.
For example: If enemy is in the portal range, user may open input portal right in front of them, stick their arm in, and at the same time open output portal in front of the enemy and choose that arm to go out. User may grab or slash at them with weapons if the arm was holding it to the enemy, even though they are at least some distance apart.
Or you can do the opposite and input the enemy's arm and output the arm right in front of you, so you can chop it off or something. However, they may pull their arm out, so careful
This ability maybe used in the defense, too. Remember, you may use input and output portal at the same time. So when your enemy is going to run you through with a sword, activate input portal in front of their face and activate output portal on their back. They will end up stabbing themselves on the back. Same principal works with guns.
Note*(Accurate representation may be found in X-Men:Days of the Future Past, X-Men Blink uses the portal in very similar way against the Centinals)
If user is master of master with this semblance, then they may do something out of a league, like literally hiding themselves inside the garage, which cannot be destroyed nor touched by the enemy. They may teleport to the random place using portals 2m at a time, or in some extremely rare cases, push the enemy or grimm themselves inside the portal, locking them up in a garage without getting the users killed.
Of course, this extreme utilization of the semblance is possible only if the user had put in efforts and time to develop their semblance to the fullest, and in most cases, it is extremely hard to achieve that kind of level. Also, this semblance does not go well with long range fighters or enemies with fast reflexes and speed.
