Ahaha, I loved reading that post!
As for their names…well, where they come from, these warrior men weren't born with their names. They earned them. Arsenik is pretty much a fancier way of writing "arsenic," the poison. Barium is named after metal because his clan likes to name their men after jewels and stones and whatnot.
You can actually learn more about 'em in this brand spanking new demo here. While it isn't a full-blown rom-com like this one is (which means as long as you laughed, I'll consider that a great success!), it's still heavy on the romance. Plus, it has a ton of animation.
If you decide to check it out, feel free to live comment like you did here! You can make it as long and rambly as you like. :) It's super fun to read and definitely helpful for me as a game developer.
