Mukai Naoya

Mukai Naoya is the protagonist of the Girlfriend, Girlfriend series.

Why He Sucks

 * 1) He is literally one of this generic harem protagonists with no charm or memorability whatsoever.
 * 2) His design is pretty much a carbon copy of Futaro Uesugi from The Quintessential Quintuplets, as both are teenagers with a short spiky hair and they are dressed in a school uniform. To make matters worse, his motivation is a little similar to Futaro.
 * 3) He is ungrateful, hypocritical and rude to his girlfriends (especially to Nagisa), as he sometimes tries to be selfish and unresponsible since he only invites them to his house just so they can sleep with him.
 * 4) * Not to mention, he left his girlfriends on a balcony on which they almost starved to death.
 * 5) He never shuts up. The way he talks is just discussing and screaming.
 * 6) Because of his personality, his character development ends up very clunky.
 * 7) He is extremely uncaring to her parents, to the point that he left the house without permission and tried to have sex with Nagisa, despite her being underage.

Redeeming Qualities

 * 1) Aside from being a rip-off of Futaro Ueseugi, his design is very well drawn.
 * 2) Junya Enoki did a good job voicing him.
