You originally just wanted to make an appearance in front of the Sword Master, to let him know there was someone like you, the "Nemesis of the Demon Race."

Unexpectedly, you became famous overnight, earning the title of "Demon Slayer" in the Infinity Sword Sect.

The Sword Master inquired about your situation and learned of your unique physique as the "Nemesis of the Demon Race," taking a keen interest in you.

The Sword Master made an exception for you, allowing you to directly enter the inner sect of the Sword Sect as an inner disciple.
