<ul>
<li>Luffy/Ruffy (One Piece)</li>

</ul>

<p>2 of the Vocaloids are the twins Rin and Len, but given the above, their names could be Rin and Ren, Lin and Len, or even Lin and Ren.</p>

<p>So where did it become known that Rin's and Len's names have different first letters, as opposed to the alternatives that I mentioned?</p>

Probably word of god. Seeing as their names are written on the software box and all.

These days there's usually a "word of god" official transliteration of character names. In the past though, it could vary depending on who was doing translation. It's more than just L/R as well. The names リン and レン correspond to a number of different western names, like Lynn and Wren.

Also, a theory for this particular case: the name's depict **Ri**ght and **Le**ft speakers/channels/whatever-it-is.
