Underworld Shun is one of the best healers in the game. He's also one of the easiest to use; just put him in battle and he'll protect the team from the start. He's very good against combos and some control teams, as he not only heals but also clears control statuses.
He also gives a double turn. Initially, it was said that he would be an EX unit, but they changed it to S, which doesn't surprise me. He is a highly recommended unit. When he came out, he was thought of as a kind of Sextans Luna with more abilities (because of the extra turn he gives), but Underworld Shun, also known as Hades Shun or HaShun, has been meta from the day he came out until today.
