I really wish MC customize some brain already.
also, took a peek on novel translation chapter listing and skim some chapters to see where we are,
afaik we're currently at chp 83/84 WN.
fan-translation stalled on the early part of new country arc at chp 97 (which shouldn't be a spoiler anymore which country is it).
I guess that would be the last arc as novelupdates mention that the WN end at chapter 105.
So, that's it, 20 WN chapters material left. looks like we're in for another 15-25 chapters to finish this manga :/ (btw ch 63 already released on alphapolis)
I wants to read the raw, but strangely I couldn't find the main series web novel...
so... I guess, see you in the next one and half year.
