Also common is the idea of soulmates, or couples tied together by fate. Syaoran and Sakura (featured in both "Cardcaptor Sakura" and "") are among Clamp's signature couples that best fits this representation. As also seen in "Magic Knight Rayearth", three girls are bound together by fate to save Cephiro. Fate is also the reason the three girls consider each other "sisters"; another idea that elaborates people being tied together (family cannot be chosen). Clamp also explores the idea of chaste or pure love (as in the manga "Chobits"). Clamp's disregard for sex or gender (or at times biological age) in these couples has led them to write same-sex couples into many of their manga in contrast to many other manga artists (for example, Tōya and Yukito in "Cardcaptor Sakura"). A number of such couples have been shown together across parallel dimensions in the Clamp multiverse. Although Clamp often writes romantic works, Ohkawa has mentioned that she feels that it is more putting one's life on the line than love that causes women to grow or change. Clamp never features love as a central theme; Ohkawa stated in an interview with Takeshi Oshiguchi in 1997 for "Animerica" that she is not "good at love stories" since her "idea of a relationship is different from that of a lot of other people".
