Encountering Iphi again
As someone who bore ill feelings against Azzy because of her sister, she certainly remembered him.
No, it's not just because of her sister. It's also because of her pride. A couple of months after Azzy's encounter with Sapphire, during a special week that was allotted to only the Elite division, Azzy and his fellow schoolmates went to Myelin city.
There, by coincidence or by deliberate planning, he once again encountered Sapphire. This time, her sister was also with her because of the last time.
But, what both of them faced is a blatant rejection as soon she offered him the position of Royal knight and nobility.
Sapphire even compromised by offering him a chance to be one of the disciples of a high-rank-9 expert but Azzy didn't even give a thought and directly rejected the offer one more time.
