After the Guardian of the 20th Floor was defeated, Jason noticed that there was still some time before the speed bonus would run out.
At the same time, Byakur was reluctant to enter the soul world, fearing that Jason would never use it again and simply dump him inside if it were to disappear.
This caused Jason to smile dryly, wondering to what extent his soul imprint had allowed Byakur to obtain sentience.
It was an interesting sight, and Jason also realised that he couldn't simply abandon Byakur.
That wouldn't be right, even less because Byakur was a craftwork of his late master, Shane.
Furthermore, he didn't think that he could easily repeat forging a soul weapon without having refined materials for the process.
Right now, he would only be able to forge some strong weapon, but they wouldn't give him the same feeling of being an extension of his arm, let alone the same runes.
