The artstyle is just stunning. You can tell the author have a lot of experience in drawing. Because finding a simple artstyle is way harder than it looks. Every line looks so expressive. It's very satisfying to look at.
I love the chemistry between the characters. Hero is just too cute, adorable and wholesome. Demon king is also very adorable in his own way. I ship them so so much i dont know how to drscribe it. Just look at how our hero boi gave a "hat" for Mr. Stay's horn. Mr. Stay didnt want to admit he liked it too lol just too cute.
