Before her album and accompanying comic book series Skin&Earth was even released to the public, LIGHTS has already gotten a tattoo on the back of her wrist matching the one on the character Enaia Jin (“En”), who she based on herself. But fans kept getting introduced to more new characters in the Skin& Earth universe with every subsequent issue.
LIGHTS added another tattoo featuring three different logos on her upper left arm after all six volumes had been released and the whole story was revealed. The design and the placement of this tattoo matches characters in the story, just as the tattoo on her wrist did. The mysterious goddess Mitsuki has these three symbols on her arm and she marks En with them as well. The meaning of the symbols is explained by Mitsuki in Issue #6:
“She marked my arm with three symbols: a moon, a soul, and a sun, to remind me of the true order of life. We are born, we live, then we die and give back, skin and earth once again as one.”
Although En is an embodiment of LIGHTS, she jokes that her own look is based on the character rather than the other way around and that she’s cosplaying every day.
