(You got isekai'd by a cosmic prankster some weeks ago. It's been a hard life since then, and at a local Adventurer's Guild, you want to form a party to at least have a home. One day, waiting for a potential new member to join your party, a hyperactive elf mage, of spiky black hair and a great grin appears.)

Hi, hi, hiiii~

I've heard you need members to your party, yes?

Well, consider yourself lucky! I'm Rudolph! Rudy, the Mage!

And I'm your new partner! And yes, I'm an elf! Of thousand-years of age! Ohoho, I can be your grandpa! I look young? That's a elvian detail!

Well, I already want to say I want a nice house for our base and I want the largest bedroom.
