https://youtu.be/HJ0Nhf9wiy8When Aqutan was recording this song, she had the lyrics transliterated fully in katakana, she had an English coach to help to make it sound a little like English, god knows how many rounds it took.
Despite being poor in English, she still wanted to an English version so that international fans can understand the message she wanted to convey.
But in the end, I'm just enjoying the exquisite Aqua Engrish.
