Consider staying overnight at KIX as by the time you go thru airport formalities, most transportation services will be reduced.
The next morning, you can travel from KIX -Hiroshima easily.

If you used the link I posted above, you could have found out that the last train connection of the day from Kansai Airport to Hiroshima departs the airport at 21:25. So, I am afraid you won't be able to make it to Hiroshima by train within the day. You could stay overnight at the airport or in central Osaka.

Not to forget to add the time needed to clear immigration and customs. And also a possibility of your flight delay. Option one: stay the night, and take the train to Hiroshima the next morning.
