Ueno

Ueno (上野 Ueno) is the protagonist of Ueno-San wa Bukiyou. She is the current president of the Science Club. Her inventions and how she uses them on Tanaka form the episodic structure of the story.

Appearance
Ueno has red hair tied in twintails. These will vary in length and react with her emotions, typically embarrassment. In her first appearance, they are notably shorter.

Her eyes are red with large white pupils. These will sometimes change to have multiple rings, or spirals depending on how she is feeling. Her pupils will change to hearts when she is feeling "romantic."

Ueno has a fang on the left side of her mouth.

Her outfit is a typical school uniform. Her scarf and shoes are red, indicating she's a 3rd year.

She used to always wear tights until Tanaka said they smelled. Now she will only occasionally wear tights, such as in Chapter 20, or nylon stockings hooked to a Garter. These aren't always colored in by Tugeneko, so it will appear she has bare legs.

In concept art, she was drawn with a lab coat.

Personality
Ueno is a brilliant inventor, bringing in a new device to every club meeting. However, she is smitten with Tanaka and many things she invents become schemes to put Tanaka in a perverse situation with her. She often does this with the idea that he will notice her. These plans almost always backfire, and she becomes frustrated or embarrassed at the situation she's put herself in.

She is often angry with others, and will call Tanaka stupid often.

She also will provide inventions to the other club presidents when they ask her.

History
Sometime before the story, she became friends with Unogawa. It is implied in Chapter 60 that she also did gymnastics outside of school.

Also during this chapter, it is shown that Ueno was forced to join the Science club after wandering into the club room during club orientation day.

In chapter 50, Ueno uses a massage robot on Yamashita to try to get her to join the club. This backfires and Yamashita is clueless about the club.

At some point she falls in love with Tanaka and has tried to express it multiple ways before the manga starts.

Tanaka
Ueno is in love with Tanaka, but can't come out and say it directly to him. She will sometimes get closer to saying it, such as telling him he's being confessed to in Chapter 1, or suggesting they "repopulate Earth" in Chapter 48, but has never said it forthright. Instead, Ueno tries to get him to put him in compromising situation to make him love her. These mostly lead to more frustration for her, though some have brought them closer together.

Based on Chapter 70, it seems Ueno was initially annoyed by Tanaka when he joined the Science Club. She gets angry at him for watching her complete her watering machine Sprin-Kun. At some point before the Christmas of Ueno's 2nd or 3rd year (based on Chapter 1's image of Ueno wrapped in ribbon with a Santa hat,) Ueno fell for Tanaka. Chapter 1 may imply she started to like him when Tanaka said he was "fine with just the two of them" being in the Science Club. This initial dynamic has lasted, though, and Ueno still yells at Tanaka a lot. This is a Tsundere trait.

Yamashita
Ueno makes plans for most experiments with Yamashita. In this way, Yamashita acts as a wingwoman to Ueno, sometimes at a monetary price.

Unogawa
Ueno and Unogawa were friends before middle school. They did gymnastics together outside of school, but Ueno joined the science club instead. Unogawa is familiar enough to comment on and touch Ueno's body.

Female Club Presidents
Ueno seems to have a friendly relationship with the other female presidents. She has created an invention for some of them. Despite this, she hasn't directly revealed her crush to any of them yet.

Puns
Many characters have names that, when grouped together, form a pun. Ueno is part of the following group(s):
 * The names of the science club members, Ueno (上野), Tanaka (田中), and Yamashita (山下) each contain a character of the phrase 上中下. This phrase loosely translates to: top (上), middle (中), and lower (下), referring to the age of each member.


 * The "cultural" clubs (basically clubs that aren't for sports) headed by female presidents are the Symphonic Band, the Science Club, the Calligraphy Club, and the Arts Club. The presidents of these clubs, respectively, are Nishikibe (錦辺), Ueno (上野), Soegi (添木), and Hanamori (花森). Together, the first characters of their names form the Chinese idiom 錦上添花, which is similar to the English idiom "The icing on top," meaning to make something good even better. Or in this case, to make something beautiful even more beautiful.
