So, there are these invisible monsters that feed off of negative emotions. If these monsters grow powerful enough, they can influence human behavior, which results in crimes like murder.
There's a small number of people who have the ability to see and fight the monsters. Only females can have this power. The show is about the magical girls who can see and fight the monsters.
Their power depends on how many admirers they have, so the magical girls are usually pop idols. All of them are actresses, singers, models, super-popular bloggers, and things like that.
Their power gets weaker when they're far away from their fans, so the Japanese magical girls stay in Japan, the American magical girls stay in America, and so on. Are you getting all of this?
If they stopped being popular, then they would lose their power - so they have to juggle their public celebrity life with their secret magical girl life. That's where it gets interesting.
The protagonist is a girl named Miyuki who isn't a celebrity, she's just the most popular girl in her school. The other magical girls look down on her because she's nothing like them.
The show is about Miyuki's struggle to cut it as a magical girl even though she's relatively weak, and none of the other magical girls respect her. Trust me, man, this show is freaking amazing.
I don't want to spoil it, but it gets REALLY GOOD once Miyuki starts getting stronger than some of the veteran magical girls, and they start...ah...just trust me, you NEED to watch this show.
One of the main characters is a swimsuit model who has millions of fans because she's super busty.
Magical Girl Pretty Miyuki!
If you saw the show, you'd understand!
— Yaku during his conversation with Horo during lunchtime on Monday.
Dude, you NEED to keep watching. It gets REALLY good about halfway through the first season.
No, you don't get it! The first half of the show is there to TRICK people into THINKING that they're watching a typical magical girl show, and then, BAM, the plot twists start dropping!
Yyyyyes, technically, BUT! If you were planning to drop the show, then it was totally worth it! You need to understand this: Magical Girl Pretty Miyuki is a DECONSTRUCTION of magical girl shows!
It takes the concept of magical girls, and then applies it to real life. Like, how hard would your life actually be if you really were a magical girl? That's what the show is about!
Yeah, but, Miyuki does it differently! Trust me, dude - truuuuust me! Keep watching. You NEED to!
— Yaku during his conversation with Horo during lunchtime on Tuesday.
Have you been watching it?
That's what makes it so good! It lays out all these tropes, and then it SUBVERTS the tropes!
I can't let you drop the show, dude! I need you to know that there's a payoff coming soon!
You don't get it, dude, you just don't get it! The show's creators are brilliant! Geniuses!
Oh man, I can't WAIT until you hit episode 7. I wish I could see the look on your face...
— Yaku during his conversation with Horo during lunchtime on Wednesday.
Aaaaand? Aaaaand?
No way. You're just trying to ACT like you're unimpressed, but I know it surprised you!
— Yaku during his conversation with Horo during lunchtime on Thursday.
DUDE! Seriously?! Wh-what was your favorite part?!
...Okay, yeah, but...what about the character development? The plot twists? The subversion of popular tropes? The deconstruction of the magical girl genre? The deep, philosophical introspection?
...but...but...deconstruction...'re not don't DESERVE to watch Magical Girl Pretty Miyuki!
Don't talk to me.
— Yaku during his conversation with Horo during lunchtime on Friday.! You remember that old fairy tale about a secret magic academy hidden somewhere in Europe? Uh, a school for witches and wizards?
Well! In the 1980s, when Saikou Corp started making video games, they created a game series called "Yanvania" which is based on that old fairy tale! It takes place in the magic academy!
The tenth game in that series, "Senpai of the Night", is the most famous one! That game was an absolute masterpiece! It's the undisputed Game of the Year for 1997!
The remake just came out! A retro classic, re-mastered to meet the standards of modern's a dream come true! I've sunk about 16 hours into it so far - it's basically flawless!
In a recent interview, the writer for the original game was asked about the inspiration for the game's story...and he gave an answer that differed from anything he ever said in the past! The writer said that the game's story was given to him by someone who claimed to be a descendent of a witch that attended the magic academy, several hundred years ago! He flat-out stated that the story in Senpai of the Night is...non-fiction! It's an actual historical account of something that really happened, hundreds of years ago! That's not even the craziest part! After being available online for less than 24 hours, the interview was taken down and replaced with a version that didn't include the writer's statement! You can still read the original version of the interview with archiving tools, but the website is refusing to answer any inquiries about why the interview was edited and re-uploaded. A lot of people suspect that Saikou Corp is trying to cover something up! Like, they're trying to...hide the fact that the magic academy was a real place that existed in the real world!
...well, I mean...ah, uh...that, that's not really...
Yeah,, uh...what, wh-what if, like...tch! You're no fun at all, dude.
— Yaku during his conversation on Monday
Wow, that new episode of Magical Girl Pretty Miyuki was wild @-@
