Give me some suggestions.

I am making a Fanfic in webnovel where MC gets reincarnated as a Vampire as he wakes up just after Veldora destroys Night rose.So, as he will be appointed as Human handler who will work with Louis and handle humans and western nations. Kinda like Inqusiter, so as Hinata will be sooner or later be under him. Now here is the issue, if I don't save Shizu everything is gonna be easy but the thing is I indeed want Shizu to live in my fanfic.

But if Shizu lives, Rimuru won't get a human form and most importantly the Unique skill- Deviant which is very very important for him to get power.

Give me some suggestions how to manage this.
