NGL this chapter is all kinds of stupid.
The whole draining a person's mana core issue is way too easy to abuse and should have killed a significant portion of the general population.
Why is Shiro, who reacts violently to a male's touch, in the MC's lap for part of the chapter, then suddenly at the end back to freaking out...
Random slave abuse then we are now organizing what ammounts to a cage match because the stuck up noble trap can't stomach an albino beast kin slave learning magic.
I truely do want to trun off my brain and just admire the set of well drawn tit's, but fuck, the author of this manga makes it hard to enjoy it.
