Giving Midnight Suns gifts is a great way to forge alliances and raise your friendship level. Having a team that works together effectively is vital if you're planning on defeating Lilith and her army of Fallen. As your friendship level rises, so do your rewards, and, eventually, you'll be able to unlock Abbey upgrades for you and your team.
If you want to unlock the Midnight Suns costume for every hero, you're going to have to max out your friendship level with each team member. While the bulk of this is achieved by running missions together and hanging out in the Abbey, you need to utilise gifts to get the most out of your time together. The real victory in the turn-based strategy game, it turns out, is the friends you made along the way.
