Manako

Manako (マナコ) is a Monoeye and member of the M.O.N. who serves as the team's sniper, due to her keen vision.

Appearance
As a Monoeye, she has one eye instead of two, she has short, shoulder-length bob-cut black hair and wears her standard M.O.N. uniform.

Personality
She is somewhat shy, and somewhat depressed; worried she was placed out of range because her teammates didn't like her.

When she is with those who are close to her, Manako is usually withdrawn, shy and only speaks to others when they speak to her. She claims to not do well with crowds of people and is prone to hiding herself as well as bumping into few objects until someone escorts her.

Manako is also very self-conscious about her eye, to the point where she is convinced the world hates Monoeyes. That is until after her date with Kimihito, when she begins to act flustered and believing that there are people like him in the world who like Monoeyes.

She is also quite self consious about her bust size. The knowledge that Centorea was too big to fit properly in a 103cm bra put her into a state of shock.

Skills and Traits

 * Advanced Eyesight: Because of her large eye, Manako possesses eyesight far superior to that of any known species. She is capable of viewing, in great detail, events happening 2 km away. Unfortunately, with one eye comes poor depth perception compared to other species with two. This makes Manako rather clumsy when navigating three dimensional spaces in her immediate vicinity.
 * Sensitive Eye: Due to the fact that her one eye is quite large, it dries out rather quickly. It also makes it easier for things to fly into it. Because of this, she uses a lot of eye medication. She also doesn't like the muzzle flash of her rifles.
 * Agility: It is hinted that she is very fast, as she managed to cover the 2 km distance from the rooftop to the store on foot in a matter of minutes, and stated it would've taken less time if her large gun hadn't slowed her down.
 * Marksmanship: Likely because of her great eyesight, Manako is a superb sniper and a master marksman. Without a scope, she was capable of shooting the guns out of the hands of people 2 km away. However, she herself admitted she has trouble aiming accurately when she has to use a silencer.
 * Stamina: Even after running 2km in a very short time while carrying a large and heavy gun, Manako wasn't even slightly tired when she arrived at her destination.
 * Weapons Training: As MON's sniper, Manako has knowledge of the use and operation of many firearms, especially rifles. She has access to prototype weapons, like her suitcase rifle, that even M.O.N.'s weapons expert, Zombina, does not have access to.

Plot
She and her team were first called in to deal with a gang of Orcs that had taken over Libido Dojin. She sniped all their guns from a distance before joining the rest of the team. They later came to Kurusu's with Sumisu for dinner.

Later when Kurusu caught a cold, Sumisu took time out from her heavy workload to "treat" him herself, leaving Manako and her group to do all the work themselves. While she stated it was to keep the other girls away from Kurusu while ill to avoid a viral mutation, she simply wanted to slack off. However, when she caught his cold, her coworkers refused to help her for the same reason.

The M.O.N. were assigned to apprehend Ranchera, Manako attempted to snipe her but missed, resulting in her escape. Later on they tracked her down to a warehouse where Sumisu agreed to having her transferred to Kurusu's household.

Later on, when Kimihito was sent a death threat, M.O.N. were assigned to act as gaurds while Sumisu went on a "date" with him, however the operation failed when Miia and the rest of the girls arrived.

The M.O.N., excluding Doppel, decide to each go on a date with Kimihito after receiving a second threatening letter from D and in order to see whether or not D will appear while Kimihito is alone or with a girl. Manako was the third and last to date him. While Kimihito was looking for something to do, Manako was keeping her distance from him due to being nervous around people close by. He tells her to be closer to him since they are on a date, but she was unable to get closer due to hiding herself with her hat, causing her perception to be compromised and resulted in her bumping or crashing into solid objects. Claiming to be no good in crowds, she then asked to be somewhere where there are less people. After finding a less populated area, Kimihito offers her some tea while claiming that crowded areas can seem tiring. Manako ponders his kindness as he is the only person who treats her like a normal person, unlike so many others she was acquainted with who usually avert their eyes out of fear or disturbance. She wonders if he does so because he has no choice and is really afraid of her and the others. She asks if he cares to look at her assuming that he wouldn't, however Kimihito looks at her with complete concern and Manako becomes very flustered when he looks at her normally.

It was during her date that M.O.N. discovers someone watching them and they all attack and restrained her only to discover that it was their teammate Doppel in disguise as well as realizing that she was the one who wrote the letter. Afterwards, Doppel asks if they all had a good time with Kimihito. Manako felt a bit embarrassed because Kimihito treated her as if she was a normal girl, but was happy he did so.

Zoological Classification
Monoeyes ( 単眼種 (モノアイ), Monoai, lit. "Single Eye species") are humanoid beings that possess the notable feature of only having one eye.

Monoeyes are able to see objects up to 2km away without assistance; however, they have poor depth perception, making it difficult for them to navigate 3-dimensional spaces, and their eyes require constant protection from harsh environments as their size makes them susceptible to dryness and allergies.
