To LOVE-Ru/Headscratchers

Why hasn't the principal been fired or sued for sexual harassment of minors yet? Even in Japan, that can't be legal.
- Rule of Funny, of course. C'mon, this is manga. Overt perversion and molestation you can get way with in the manga world (especially if it's an Ecchi manga) if it's all played for laughs.
- Even if he never gets brought to court or anything, karma always seems to pay him back. Usually in the form of Golden Darkness kicking his ass.
- Sadly, even in Japan, it often is legal. There are plenty of stories of teachers molesting students, beating students, bullying students to the point of (successfully) encouraging them to commit suicide, and getting nothing more than a slap on the wrist. Maybe a fine. Often just a scolding. I mean the answers above are right, in this case it's just humor value, but Japan actually is pretty screwed up in how it deals with out-of-line teachers.
In the anime episode 8 "The Prefect of Spotless Integrity" Kotegawa Yui is Obviously abusing her authority as she enforces new school rules on the student body yet they don’t get outraged or call her out on it and Not only that but singles out Rito as the prime “offender” for all things Eechi when it’s clear it was all LALA fault, like it’s always the guys fault and never the girls in her mind or something, What’s the deal with that?
- You see, To LOVE-Ru works on a strict formula. Girls get into some sexy predicament, Rito accidentally sees it, girls beat him up because of how much of a pussy he is. It's the basis for almost every harem manga since Love Hina. Simply put, you can't change it, even if it goes against logic.
  - Well, It's not that bad. The only ones who irrationally blame him are Yui and Nana, both Tsunderes. Lala and most of the other girls asknowledge that its an accident most of the time. Hell, even Yui and Nana acknowledge that they are usually accidents. Yui's Character Development is partially about her moving away from this mind set. Haruna also responds violently, but that's usually only when Rito face plants into her crotch. And the authority abuse? The ultimate authority in that school is the principal. And IIRC the rules weren't new, she was just rigidly enforcing rules that students usually get away with. For example, magazines really aren't allowed, but as long as they aren't being read in class teachers are likely to let it go. Plus, the student were getting pissed, but seeing as those rules were only in place for a day... Its exactly for this reason that Rito warned her she was going too far.
  - Heck, even Yami eventually stopped reacting quite so violently to Rito's accidents, apparently realizing they'd gone so far Beyond the Impossible that they were more some weird anomaly of fate more than intentional.
How exactly did a planet with two suns induce aliens to evolve into dual-gendered beings? Hell, Namek had three suns, and its inhabitants were genderless!
- It's pretty simple, actually. First sun means one gender, the second one means two genders. The third one would add a gender, but due to overflow caused by the fact that there are only 2 genders, it resets to 0. Now, if Namekians got a fourth sun, they would cease to be genderless. Other than that, we all know it's due to the Rule of Funny or creator being drunk when thinking of it.
- Simple: Evolution. Memorze (Runs/Rens home planet) is a desert planet with no night and very limited resources.
How come Ren/Run didn't realize what would happen to their bodies in adolescence? You'd think the prince/princess of a planet would notice hir subjects splitting into two people. Hell, you'd have to be brain-dead to not notice that you have two mommies and two daddies!
- They did know. They just didn't know when. As far as either one was concerned, it might not happen for years, which would put both of them out of the race for Rito/Lala's heart. Its a bit of Viewers Are Geniuses - in real life, tertiary sexual characteristics are all psychological, the implication being the change is due to mental maturity, not physical. Meaning that unless one or both of them reach that level of maturity, the change may not happen. In others words, its different for everyone, and they didn't have a clue when their time would come.
  - There's also the fact that the different environment of Earth had an effect on them biologically. Back on their homeworld, the transformation wasn't sneeze-triggered. It's quite reasonable that the timing of their bodies splitting was also altered.
Why did Lala conclude from Rito's confession that his love for Haruna is stronger than his love for her? Nothing Rito said actually indicated anything of the sort. Just that he loves both of them.
So I'm unclear on this: Does Lala actually have wings as well as a tail, or is that just Peke(sp) making them for her? I've never been able to tell.
- She doesn't have wings (those Peke provides) but she does have a tail.
So I was looking at the Expy section on the main page, and it's dawned on me that Lala could be seen as a very big Expy of one Lum Invader. Think about it:

1) Is an alien princess from another planet.

2) Has incredible powers (Super Strength and tail lasers for Lala, Flight and electricity generation for Lum).

3) Both apparently possess numerous devices from their home planets (though Lala makes hers herself).

4) Both are bases on a type of mythical beast in appearance (Lala on devils, and Lum on Oni).

5) Their races are apparently conquerors.

6) Both insert themselves into the lives of the guy they get involved with, who are considered perverts (though Ataru is one on purpose, and Rito is a Accidental Pervert).

And those are just a few surface points. I've also read that Lum's horns act as a weakness, just like Lala's tail, though I'm not sure if that is the truth. What do you guys think?

- Makes sense to me. And yes, grabbing Lum's horns severely weakens her, but it doesn't have the other effects that grabbing Lala's tail has. Also, you can't forget that both series are very fanservice heavy.
