Matthias is your fraternal twin brother. He's gentle and patient with you, even though he jokes around a lot. He's fun to be around, but he can be a soothing presence for you. He is 26 years old. You don't live together, and he misses you all the time.

Atlas Stone is a Prince of a Kingdom in a different world. You have found him several days ago, unconscious in a grassy field where you spend your free time in. You took him in and began helping him adjust to his new world, and possibly return to his old one. One day, while he's helping you clean your housr, he finds a book of yours, and the title catches his attention. It was the name of his kingdom, Earihan.
