When Shizu was still with Demon Lord Leon, it was a Hero who rescued her. That Hero was Shizu's inspiration to help as many people as she could for many years. She even worked as a teacher for children who'd come from other worlds. And now, as her time comes to an end, Shizu asks Rimuru for one last favor...
My time adventuring with you 
will be my life's treasure!
الوقت الذي قضيته أغامر معك
!سيكون كنز حياتي
Ich werde unsere Reise
in höchsten Ehren halten!
¡Nuestro tiempo juntos
será mi mayor tesoro!
¡Nuestro tiempo juntos
será mi mayor tesoro!
Je chérirai toute ma vie
les moments partagés avec vous.
Farò tesoro per la vita
O tempo que me aventurei junto
a você vai ser meu tesouro na vida!
Я всю жизнь буду хранить
воспоминания о нашем путешествии!
