Time Stranger Kyoko, Vol. 3
Kyoko has found all but one telepath and is near awakening her sister. However, Hizuki can no longer hide his feelings for Kyoko and kisses her--a crime punishable by death. Now the only way to save his life is for Kyoko to accept him as her betrothed!
Kyoko Suomi is the princess of Earth in the 30th century. Kyoko lives among the commoners, unwilling to reveal her true identity and ascend the throne. The king will allow Kyoko to live as she pleases if she can revive her twin sister Ui, who has been trapped in time since birth.
