Hands off, Touma. Serval was already taken by Kaban and You have your own harem.

There's a meme where Index / Railgun characters salute the dying Kemono Friends by pressing F

If I'm not mistaken, this is a reference to that meme

Wouldn't imagine breaker activate here and make serval back into a serval cat?

If we're talking about how Imagine Breaker works, then the answer is 'it depends'. Sandstar can turn remains or even inanimate objects into Friends as long as it contains some information on the subject so you might not end with a live Serval cat.

But yeah, this is basically another personification of AIM field artificial angel kinda topic.
