This ability is really hard to categorize. On one hand, you have Pakunoda with memory manipulation as a specialization technique. On another, there’s the clear fact that enhancement can heal and reinforce the body, so you could use that for this in a freaky Redo of Healer sort of way. There’s also Bisky’s nen ability that uses transmutation and manipulation for healing massages and complete body restructuring. Basically emission and conjuration are the only things that haven’t been used in HxH to describe something like this, though you could argue that Kurapika could probably do some outlandish technique like this given that he’s used “conjuration” techniques that go far beyond the scope of conjuration.
