Haruyo is a (somewhat) normal Pekoponian girl, and Sumomo's Pekoponian 'partner' of sorts. The two's relationship is... less than pleasant, but Haruyo tolerates it, if only because the alien helps her dad's writer's blocks.
She is a romantic idealist, though she hasn't been on a single date in her life. She isn't really obsessed with finding a boyfriend, though she would really really like to meet the right person soon...
Haruyo is a bit high-strung, a trait she definitely got from her manga-ka father. She's somewhat moody, and can go from exaggerated hot-bloodedness to gloom and doom in half a second if the situation is bad enough.
For now, she's trying to pretend that she doesn't notice all the aliens around, under the false pretense that if she "ignores them, they will go away". So far, it's not really working.
This will be worked on in a bit in the future.
If you don't know who this is, check out volume three of the manga, the bonus chapter~

Genre Savvy - She tries to be this. Whether she's successful or not varies.
I Just Want To Be Normal - What kind of normal high school kid has an alien in their house?
Love At First Sight - Kind of -- she couldn't have spoken with Fuyuki for more than a half hour, but she already wondered if she'd fallen in love with him.
- In Love With Love - But it's possible she was just suffering from this.
Love Bubbles - Her daydreams usually have these.
Monster Roommate - Well, alien housemate. Same difference.
Naive Everygirl - Though it kind of fits, she doesn't suit the tropes as much as she thinks.
Overprotective Dad - He didn't seem to keen on the idea of Haruyo finding a boyfriend.
Parental Obliviousness - Though Haruyo's dad can be forgiven for not noticing the alien that broke in to their house (since he was desperately trying to work through a writer's block at the time and probably wrote the noise off as Haruyo's... personality) he still didn't seem to think much of how Sumomo bothered Haruyo...
Role Playing Game - She is quite fond of the video game variety.
Theme Naming - "Haru" means spring -- which seems to go along with Winter (Fuyuki), Summer (Natsumi), and Autumn (Aki).
