Notably known for her opening and ending themes for various Key visual novels, one of Lia's most prominent songs has to be "Toki wo Kizamu Uta." Otherwise known as Clannad: After Story's opening theme, an anime favorite of mine.
Being one of the most beloved series in anime history, Clannad: After Story's opening is probably my favorite anime opening, by far. And I think a lot of it has to do with the emotional attachment I have towards this anime. But I'm not the only one. A lot of people even remotely affiliated with anime have fallen victim to the sentimentality that comes along with this series. And being the opening theme to the anime's second season, Toki wo Kizamu Uta represents the story's best season - because it is this part of Clannad that truly makes this anime an unforgettable one.
