A Big Question And Vote Of Choice

So I was basically asking if after Izuku died after saving sister and reincarnating in the Cardinal world do i

a.) wait for rimuru to grow into his true dragon version and his fight with yuuki to let him come to the MHA verse

 or

b.) in the middle of the cardinal verse like Charybdis arc or the orc lord arc and other in between storyline to balance it out.

This is very important in my fanfic, so choose without forgetting that the timeline will be changed heavily, and only some important time checkpoints will remain same in meaning but different ways to achieve the same result.

So Which gets more votes, I choose that

so go for it.
