In my opinion Rimini was at least a+ when he reincarnated at first because in volume 5 of the light novel when veldora was released from the seal rimuru had him hold in his magicules because he was afraid that the monsters in the town couldn’t handle it.

This is based on what veldora says about even demons not being able to approach him in the caves, so I assume that he is talking about either a greater or arch demon both of them being somewhere between a- to a respectively

Now since in the beginning rimuru had no problem being around veldora which means that he was at a rank where he could survive being around veldora.

However this is all speculation and can easily be overlooked as the fact that since slimes live by absorbing magicules from the surrounding environment that it would give them a high resistance to areas dense with magicules.
