The Brilliant Healer's New Life in the Shadows: Volume 4 oleh Sakaku Hishikawa

Now that the situation with Liz has been resolved, Zenos shifts focus to researching the Black Guild. He soon learns of an important figure within their ranks who is supposedly able to heal any malady. Suspecting this might be his childhood friend Velitra, who once studied under the same mentor as him, Zenos decides to look further into the matter. Zenos suspects that Velitra has their old mentor’s notes. If Zenos is correct, his old friend might also hold the key to finding out more about the mysterious man.

Unfortunately, the Black Guild is shrouded in mystery, and information on their executives is guarded closely. Left with little other recourse, Zenos seeks out an information broker to help him gather the knowledge he seeks.

Will Zenos manage to infiltrate the Black Guild? And if he does, what secrets will his prying reveal...?
