Yuka's Progression

Asphyxiation
Rank: F
Effect: By producing carbon dioxide and manipulating it using her quirk Yuka can effectively cause a person to slowly become oxygen deprived which can cause them to receive external damage over time as long as they stay exposed to the toxic air. [Harm (Burn)]

Inflation
Rank: F
Effect: Yuka is able to inflate her body partially, allowing her to hold much more air in her lungs than what would normally be possible. This elasticity has been applied to the rest of her body as well which makes her slightly more durable than your average person.[Durability]


Quirk (Living Breath)
Rank: C Rank
Effect: Yuka was born with an extra organ that is a little over twice the size of the others. In her specific case, this effectively an extra lung which gives her super lung and breath capacity. However, the really unique ability comes from this is her ability to produce specific quantities of lilac-colored air, which can be oxygen or carbon dioxide-based, that she can control in a way akin to air manipulation found in other quirk users.

Through the use of hand movements of even mental commands this specific air that she breathes can be utilized in many different ways from creating a vortex of wind to even using it as an updraft to cushion a fall. She can produce as much air that can be controlled in order to fill up the full radius around her (Using Range of her Rank). While it's normally not tangible just like regular air it does have some unique properties not seen and aspects of it that can be altered at Yuka's discretion. For starters, Yuka can alter the composition of the air she breathes to be either Oxygen or Carbon Dioxide depending on her own needs. While oxygen works primarily like normal air or wind that the average person breathes in when she utilizes carbon dioxide this can be used for more debilitating purposes for her enemies making it much harder to breathe if they're inside the radius of her quirk's influence. She can also 'solidify' her own breath slightly in order to make it tangible enough to stand on or touch which is useful in capturing objects or assisting people and as she's gained further utility she can coat herself in her own air and use it as a cushion for blows increasing her durability.

As a byproduct of this special type of air manipulation, Yuka has effectively gained the ability to exhale and inhale at superhuman speed and strength. She has incredible lung power and can suck in air like a high powered vacuum as well as expel at the same velocity and force. This often allows her to draw people and objects towards herself as well as produce enough force to send people and objects flying away from herself. To an extent, this even works on herself as if she's airborne she can use the vacuum forces to bring herself closer to the ground or exhale in order to push herself further away from it even if these are very one-dimensional tricks.

Yuka also has incredible stamina when it comes to inhaling and exhaling as well. She can exhale for several minutes at a time depending on how much air she has stored in her lungs previously and the same could be said for inhaling as well. To compensate for her powers her body has a slightly more durable elasticity than your average person which while providing some defense is mostly an adaptation for when she inhales it allows her torso to stretch to hold much more air than normally possible.

The final and most unconventional of her abilities is Yuka's unique ability to breathe in and survive off of both oxygen-rich air as well as carbon dioxide. Her extra lung has the unique property to be able to absorb carbon dioxide harmlessly into her body which effectively means that she can 'hold her breath' for an extremely long period of time as long as has air in her lungs to begin with since this process is very slow and deliberate.


Benefits

Strength - Whether inhaling or exhaling the strength of Yuka's technique is around 3200kg worth of force in either direction able to blow things under this weight off their feet or draw them in. Yuka herself is rather strong as well due to her very oxygen-rich body and is able to lift such an amount herself because of this.

Range - The range of her breath based attacks as well as air manipulation can reach a maximum of 30 meters from herself. Anything farther than this set range wouldn't feel the effects of any aspect of her quirk.

Stamina - Yuka can upkeep her inhalation/exhalation for several minutes (posts) at maximum strength if need be. She also doesn't physically tire very easily due to her ability to process both oxygen and carbon dioxide as well as being able to do most physical things at her upper limit for a maximum of 6 posts.

Pressure
Rank: E
Effect: By producing carbon dioxide and manipulating it using her quirk Yuka can effectively cause a person to slowly become oxygen deprived to either pinpoint or create a field around her which slows the moments of everyone in her radius of influence [Affliction: Speed]

Elasticity
Rank: E
Effect: Yuka is able to inflate her body partially, allowing her to hold much more air in her lungs than what would normally be possible. This elasticity has been applied to the rest of her body as well which makes her slightly more durable than your average person. She can also coat herself in her own air and provide some cushioning which makes her more durable at the same rank, but in a different way.[Durability]

Air Detection
Rank: E
Effect: Yuka's powers have evolved further in that her sensory abilities have been enhanced by her quirk in a way that she now has a detection zone around her in which she can feel subtle changes in air quality and movement allowing her to detect hidden people or objects. Her eyes are also more accustomed to picking up finer details allowing her to much more easily discover discrepancies in the costumed folk who try to deceive others. [Enhanced Senses]

Inspector
Rank: F
Effect: Through her training and fieldwork, Yuka has developed quite a keen skill in investigation. She is highly sensitive to the world around her and uses this to her advantage noticing subtle changes in her environment and her ability to track others from clues left behind is nothing to laugh at.

Benefits

Damage/Strength/Burn - Whether inhaling or exhaling the strength of Yuka's technique is around 3200kg worth of force in either direction able to blow things under this weight off their feet or draw them in being able to smash through metal with just her breath alone. Yuka herself is also rather strong as well due to her very oxygen-rich body and is able to lift such an amount herself and can even harm others by eliminating oxygen in the area causing them to take damage over time.

Range - The range of her breath based attacks as well as air manipulation can reach a maximum of 30 meters from herself. Anything farther than this set range wouldn't feel the effects of any aspect of her quirk.

Stamina - Yuka can upkeep her inhalation/exhalation for several minutes (posts) at maximum strength if need be.
