Even if Michael's demands were shamelessly straightforward, Alice agreed to all of them.
She wanted Tigerfang since their family didn't have many Epic Tier-0 Artifacts.
In fact, they did not have a single natural Epic Tier-0 Artifact. Tigerfang was unique, and it suited Kaleb perfectly.
Her brother had yet to turn 18 and manifest his War Rune to enter the Origin Expanse, but their parents were already working hard to collect the necessary resources for him. An exceptional Tierless Artifact was everything he was missing right now.
Tigerfang was perfect for Kaleb to bind before he entered the Origin Expanse. With Tigerfang, he would be fully prepared for the worst-case scenario. Nobody hoped that the worst-case scenario would occur, but it was always better to be prepared. And if they had the money or resources, nobody would let the opportunity to grab Tigerfang slip away.
