Hello everyone this is my first translation, and I hope I did a good job! I saw chapters 20 and 21 weren't translated yet, even though 22 and 23 were... which is weird since we're currintly in the new story arc. Maybe, if no one else uploads a translation for ch. 21, I might work on that one as well. Let me know what you think!

Your work here is great buddy. I will always welcome more translations for this author. From what I am seeing chapters 21, 24 and 26 have not been translated yet. If you choose to continue translating for this series I would greatly appreciate it!
