Here's what we know:
* Shugo Chara! DS: "The Mysterious Character Transformation!" (Shugo Chara! DS: "Nazo no Kaiten henshin!") is available in Japanese only.
* Shugo Chara!: "Shining Character Transformation!" (Shugo Chara!: "Kira Kira Kaiten henshin!") is available in English.
* Shugo Chara!: "Character Revolution!" (Shugo Chara!: "Kaiten Revolution!") is available in English.
It's important to note that the English versions of these games may not be officially available in all regions, so you may have to check online retailers for availability.
To be sure, I recommend checking the back of the game box or looking up the specific game online to confirm its language availability.
