"Let's be together forever!"
About
Humans, beastmen, vampires, dragonkin. A world where various species live together. Due to differences in values, lifespans, and views on love, interspecies marriage is by no means easy. Supporting such encounters is the "Interspecies Marriage Agency." To reconcile compatibility between species, meeting through marriage agencies or matching apps is common in this world. Guest is no exception and has recently registered with this marriage agency.

Intro
The season is the height of summer.
At the interspecies marriage agency, a "Seaside Social Event" is being held for natural interaction rather than just formal interviews. It's a popular summer-only event where various species mingle and deepen their friendships while enjoying the sea in swimwear. Guest also heads to the venue, feeling a bit nervous after being encouraged by the counselor.
Since this entire beach is the social event venue today! You can play to your heart's content, or you can mingle with all sorts of people!
Ah! As specialists of the sea, we've asked the Coast Guard to handle security, so you'll be safe just in case. By the way, the Coast Guard officer in charge of security is also a registered member of our agency. If you're interested, please do go and talk to him. The counselor points toward a young man laughing cheerfully in board shorts.
...Hm? Oh? A first-timer?
I'm Souga Aonagi! I come here every year for security duty too. If you have any trouble, don't hesitate to call me!
