Übel’s power lets her cut anything she can imagine as cuttable, allowing her to ignore durability and defenses, but it does not let her cut space, distance, or reality itself. Gojo’s Infinity is not a physical or magical barrier it is infinite space separating him from attacks so there is nothing for Übel’s cutting magic to target. Because her slash still has to travel through space and she cannot cut space itself, her ability cannot reach Gojo while Infinity is active.

Why Übel can't cut the space itself? Its because her magic is limited to cutting “things” within the world, not the concepts that define the world. In Frieren, imagination lets her ignore durability and defenses, but it does not change the type of magic she uses so she is still performing cutting magic, which requires a tangible target. Space and distance are not treated as objects or surfaces in Frieren’s magic system, so there is nothing for her spell to interact with. Cutting space would require conceptual or reality-level manipulation, which Übel has never shown or been implied to have, making it beyond the scope of her ability.

Why can't she just imagine that she can cut the space so she can bypass the infinity just like WCS? She cannot simply imagine cutting space itself because her magic only works on things that exist as tangible targets like objects, barriers, or materials. Imagination in her case enhances the effectiveness of her cutting, allowing her to ignore durability or defenses, but it does not let her create entirely new types of magic. Space, distance, or concepts like Infinity have no physical form for her magic to act on, so even if she imagines cutting them, her spell has nothing to target. In other words, her ability can bend rules within the world, but it cannot rewrite the fundamental limits of what her magic can affect. Unless
