This makes me wish I could speak Spanish. With only the visuals for context, something screams at me that the tone is just the right balance of zany and piss-take. Oddly, more so than the blunt in her mouth on the cover, it's Rei's hair curls that encapsulate this feeling for me.
If this doesn't call out it's own 'How to Draw Manga'-esk art-style in this first issue, I'd be blown away.
