Interesting. I like the female MC and her master's interaction. Too bad she kept dying.
To be honest, I'm reading this only to find out how the "bug" can finally be eradicated. I'm sorry, but to me he, the bug, does not deserve to be over powered. His decisions, his smiles is just making my blood boil. He is making decisions haphazardly. He is just doing things to inflate his ego. Even gathering his own harem. The nerve of this bug. I really want to get rid of him and then this manga will be so much better. 3/5 stars for now.
[Edit]
Thank heavens the original bug is gone. My rating is back to 4/5 stars.
