Mona Tsukishiro

* Anime
* Manga

**Mona Tsukishiro** (月城 モナ *Tsukishiro Mona*) is a character in My Senpai is Annoying. She is a co-worker and friend of Tōko Sakurai who is considered to be the craziest and most mysterious worker in the office where she seems to do whatever comes to mind first and doesn't have second thoughts about her actions.

## Appearance

Tsukishiro is a young woman with shoulder-length gray hair that is split on either side where it exposes her forehead and half-lidded light blue eyes that sometimes glow.

Most of the time, she is seen wearing a grey vest over a white-collared shirt and a grey pencil skirt.

## Personality

Tsukishiro is an eccentric coworker that tags along with the other four and she is often finds herself in weird situations. She has an unique presence and manner of speaking that her behavior and activity is quite strange like bringing a love article into the office or licking Futaba Igarashi's fingers to heal her papercut. Because of this, it seems that most of her co-workers would describe her as a weirdo.

In spite of her freaky attitude, she's a rather excitable and quirky girl with a strong fondness for vodka, to the point of carrying around a vodka bottle she claims is just filled with water and home-baking some vodka chocolate for Valentines Day.

## Plot

While walking with Tōko Sakurai, Tsukishiro notices Sōta Kazama looking at them and wonders if he wants something, but Kazama explains that he was heading to the vending machine and walks behind them. As Tsukishiro starts to get suspicious, Sakurai asks Kazama to carry something for her and whispers the vending machine is on the opposite hall.

Entering the bathroom, Tsukishiro sees Futaba Igarashi and greets her, but that scares Igarashi. Tsukishiro introduces herself and states that Sakurai often talks about Igarashi. Tsukishiro wonders why was Igarashi grinning and Igarashi explains that Harumi Takeda landed important contact. Tsukishiro then wonders why Igarashi is so gleeful over this and nervous Igarashi explains that Takeda is her superior and trained her. Tsukishiro guesses its respect for him, but as Igarashi blushes, she guesses its affection.

Mona has had some interaction with Kazama's friends, Hijikata and Oishi. On Valentine's Day, she eats the chocolate that Sakurai made for Hijikata and then cramms some of her homemade vodka chocolate into his mouth. At the office drinking picnic, she gets very drunk with Ooishi and dances with him.

## Etymology

* The name **Mona** means "noble or aristocratic" in Italian.
	+ She shares her name with the **Mona** Lisa painting.
* Mona's surname **Tsukishiro** means "moon" (月) (**tsuki**) and "castle" (城) (**shiro**).

## Trivia

* Tsukishiro expressing several Russophile qualities such as speaking Russian, wearing an ushanka during winter and putting vodka in everything hint that she might be half-Russian because of her name (**Mona**) being spelled in katakana (often seen in foreign names) and her light blue eyes (something an East Asian person won't usually have).
	+ She seems to have an interest for Russian culture and products, seen when she shows Futaba Igarashi her bottle of Smirnoff vodka, but stating she's actually drinking water within the bottle. She also greets others sometimes with Russian phrases too.
		- She uses Russian greetings such as "dobroye utro" [Доброе утро], and "dobryy deń" [Добрый день], meaning "Good morning" and "Good day" respectively.
		- Some other Russian phrases she uses includes "davay" [Давай], and "spasibo kak vsegda" [Спасибо, как всегда] (Thanks, as always). The latter only happens in the manga.
* Tsukishiro is seen to be a appear at random places frequently. Igarashi and Natsumi Kurobe spot her one time at the arcade, trying to beat her own high score at a dancing rhythm game, although she isn't very good at it. At one point, Harumi Takeda met her at the ramen shop and competed with him over who could eat the most steamed buns, but failed horrendously as she couldn't handle hot food.
* Tsukishiro has a strange ability to effortlessly make people want to do something for her without question. For example, when Hijikata and Oishi spot Tsukishiro being hit on by two other guys, she somehow subdues them into buying her steamed buns.
* Tsukishiro's first appearance in the manga was in Chapter 72 before being properly introduced in 73 while the anime introduces her in Episode 2, which adapts Chapter 2 and other early chapters. This means she also gets included in every company-wide event shown in the anime when she missed out on most of them in the manga due to first appearing so far into it.
* When it comes to drawing fortunes at Japanese temples, Tsukishiro defies statistical odds and always pulls a "Great Luck" slip.
* Tsukishiro's main color is light blue (with her eyes being the usual color coding for her in the manga), which denotes her mellow and mysterious personality.
