Why is the title written differently in kana and romaji?


Watching the anime titled [Ao Haru Ride](http://anidb.net/perl-
bin/animedb.pl?show=anime&aid=10385) (AniDB link), I noticed that the [title
screen](https://myanimelist.cdn-
dena.com/s/common/uploaded_files/1441512929-a2698347b568f40c657af0c914306d9e.png)
displays the title in kana but it is given as アオハライド or _Ao Ha Raido, Ao Ha
Ride;_ entirely missing a kana ル for _ru_

I noticed that this is already present in what seems to be the Japanese manga
cover I found on Google images:

[![Cover of Ao Haru
Ride](https://i.stack.imgur.com/Q4nnI.jpg)](https://i.stack.imgur.com/Q4nnI.jpg)

The title in kana reads _Ao Ha Raido_ while the title in romaji reads _Ao Haru
Ride_. Why this discrepancy?




From [Tae Kim's guide to learning
Japanese](http://www.guidetojapanese.org/learn/grammar/slang),

> There is one major driving factor behind the majority of slang in Japanese.
> The primary goal of most slang is to make things easier to say. In other

This would imply that the author felt that saying 「アオハルライド」is either harder or
more annoying (or both) to say in conversation than 「アオハライド」.

You can try it yourself: saying _ao haru raido_ forces you to pause between
_haru_ and _raido_ , whereas one can say _ao ha raido_ in one go.

**Update 2019:**

There's an explanation given in the first volume of the manga. Here's an
excerpt from the official translation:

> Right away people sent letters and tweets, asking about the Japanese title
> _Aoharaido_. So I'd like to be able to answer.
>

>> **Aoharaido** = youth + ride
