If I have to say, the ring acts as a proof to signify "I've received the enhancement!".

Our Admiral says too that there's no actual value or anything to the ring.

It's like a bonus gift after the procedure.

He even says you can throw it out if not needed, let alone having to wear it.

But wouldn't that make it harder to tell apart those who've received the enhancement from those who haven't?

Ah- No worry about that.

Admiral, I who actually does the surgery... and Inazuma too, are keeping all records.

The procedure isn't exactly kind to our resources, and especially, our wallet.

Huh? Weren't the first surgeries free because the Admiral secured the rings?

Though he managed to establish a route for getting more rings, we ended up paying all the necessary expenses for it.

Moreover, I, Inazuma and Admiral the three of us discussed the timing of operations every time we were about to have one.

I remember her mumbling something about "I'm finally free from this hell..."
