Ruka is hellbent on knowing the full story behind Kazuya and Chizuru's relationship, and once she does she decides to take action.
It's hard to believe Chizuru 
would let you two-time her,
،ليس معقولاً أن تتركك تشيزورو تخونها
Es ist schwer zu glauben, dass Chizuru
dir erlauben würde, zweigleisig zu fahren.
Me cuesta creer que Chizuru
tolere que le seas infiel.
Me cuesta creer que Chizuru
tolere que le seas infiel.
J’ai du mal à imaginer Chizuru
accepter que tu la trompes.
Non posso pensare che la principessa Chizuru
ti permetta di tenere il piede in due scarpe,
É difícil acreditar que a Chizuruzinha
deixaria você chifrar ela,
Не думаю, что Тидзуру 
простила бы тебе измену.
