...Celine Drior...

"There." Azazel pointed at the distance, where Kate happily talked with Kate while they were eating.

'Hmmm, something seems wrong.' Fein could feel that her sister was a bit wary of Kate. 'Is it probably my imagination?'

Why would his sister become wary of Kate without a particular reason? So Fein just shrugged this thought away. Contrary to it, Fein was happy because Fey finally has a female degu user to talk with. Although he wants his sister to become stronger. He doesn't want her to completely set aside her teenage life. 

Teenage life only happens, and when it passed it was already over. He still wished that his sister could enjoy such things and not become like him, who has an extraordinarily boring life that only pursues power.

Fein only wants the best for his sister, but at the end of the day, Fey would still be the one to decide for herself.
