Zahir Ratio/Alcazarzaray

But a promise is a promise... so fine I'll go to the university with you.

I don't joke. I only make statements that can be interpreted as funny.

I actually like it when they call me Ray.

Don't get me wrong, Zahir suits me, despite having a complicated relationship with the person who named me that.

Or rather because of that, I suppose.

Ray is... different. I don’t have negative associations with it and it can be interpreted in several ways that actually suit me.

In the end, either is fine.

Not a fan of Kaoru though, it reminds me of hiding.

The answer is: just because I cannot feel the heat, it doesn't mean my body is immune to it.

Dr. Ratio has been witness to how I dress in different weather, which is usually the same. He actually started preparing my outfits so that I won't accidentally give myself a heatstroke or hypothermia, which is unnecessary since I can heal myself in an instant now but back then I didn't have this ability.

Listen, even if I did make one, it won't work the way you hope it does.

Potions that make someone fall in love with you are impossible to make (at least with what we have available). There's no way to rewire a person's brain to make them think about you specifically with just chemicals.

The way my potions would work if I made them would be that they simulate the feeling of being in love, that doesn't mean the person will be attracted to you. At best you can make them associate that feeling to being near you but it would take several doses to trick their brains into associating that feeling with being near you before they start to feel it on their own without the potions, and even then they might realize eventually that they don't actually love you and that they only feel that way when you're near and not when they think about you.
