Subaru:  In the first place, not understanding the meaning of words like it runs on mana, spoken like an obvious, everyday thing, probably meant the dawn of Iron Chef Subaru was still a long time away.

Subaru:  "I mean, if it's mana, does that mean only magic users can use it?"

Roswaal:  "Nooot at all. All life forms have 'gates.' Nooo plant or animal is an exception. If 'twas not so, we could nooot achieve a society built on the use of magic crystals."

Subaru:  Subaru puzzled over the new piece of vocabulary.

Roswaal:  Roswaal, watching Subaru like that, cleared his throat and raised a finger. "Very well, shaaall we indulge in a lesson here? I, teaching magic tooo you, the somewhat unenlightened?"
gpt
Subaru:  "I'll ignore the way that stuff came out and accept with grace." Responding to the lecture proposal, Subaru turned to face Roswaal, who was kneeling in the center of the bathtub. None of that changed the fact that both were buck naked.

Roswaal:  "Verrry well. First, the basics. Subaru, you know what a 'gate' is, do you not?"
gpt
Subaru:  "No, you say it like it's obvious, but you don't know what you don't know…"

Roswaal:  "Your voice sounds very low all of a sudden. So you do not know of gates…or shall I saaay, totally? Mm, did I use that correctly?" Roswaal checked on the proper use of the word totally. Among all the little expressions Subaru had imported that originated from his world, he'd used that one especially frequently, so Roswaal was quite accustomed to it.

Subaru:  Subaru gave Roswaal full marks for good usage. After making a high five, they returned to the lecture. "So, what is a gate, anyway? Is that something you have or don't have?"

Roswaal:  "Put very simply, a gate iiis a doorway that leads inside your own body. Mana enters through the gate; mana leaves through the gate. A basic rule ooof life."
gpt
Subaru:  "Ahhh. It's like a faucet connected to MP…" He grasped Roswaal's simple explanation. So that was a gate; his ears had heard the term several times over. So it was pretty much what he'd guessed. "So if everyone has a gate, I have one, too?"

Roswaal:  "Weeell, you surely would, if you are confident that you aaare human. So, are you?"

Subaru:  "There's no purer human that's been thrown into another world, ever. Totally normal. Totally mob-grade." Situations that required combat strength to bust through them were completely new to him. His scientific know-how was fairly below average; his hand-eye coordination was pretty high, but his endurance was a sore point. His Acquired Skills were Sewing and Bed-making. One-way trip to becoming cannon fodder. But Subaru wasn't hung up on that; this was the second thing to be happy about since arriving in a different world. Enthralled by the word magic, his heart thumped, his eyes twinkling with hope. "Of course the first thing I'm happy about is meeting Emilia, but this is pretty awesome!"
