Wherever I go on the net I see the name of the actress that plays Makoto as Myuu. But I see on this picture something diferent.
¿Is this wrong?.

Generally speaking, Japanese names which has same KANJI(Chinese character) is not always having same pronunciation.
For example,I know two Japanese whose names are MAKOTO and Shin,
their names in KANJI are same.
In a Japanese SFX magazine, they said that SAWAI(Usagi)'s name is "MIYUU" and AZAMA(Jupter)'s name is "MYUU".
Some Japanese likes to write their name in alphabet as English-like
spelling rather than to write with obeying strict romanization rule in
casual situation, so AZAMA spells her name as "Mew".
