Overall I thought it was messy. I wasn't able to take the plot seriously and the characters were all lacking. At the start I thought it was interesting but I don't like how the relationships between the characters developed. It seemed a little too complex than necessary. The one thing I did love however was the ending. The last chapter of this manga leaves you in a cliffhanger but things are perfectly wrapped up in the Kaichou wa Maid-sama X Yuki wa Jigoku ni Ochiru no ka crossover special which is the real ending.
Yuki wa Jigoku ni Ochiru no Ka
