Rikei-chan

Rikei-chan (サイエンスちゃん, Science-chan) is a recurring character in the Getsuyoubi no Tawawa series. She is a graduate student and a close friend of Kouhai-chan and Senpai.
==Appearance==
Rikei-chan is a young woman with short, dark, messy hair that hangs just barely above her shoulders. She wears a white lab-coat over a green striped turtleneck sweater along with navy-blue jeans, and oval-shaped glasses. And, like all other female characters in the series, she has rather large breasts.
==Personality==
Rikei is a highly intelligent young woman who has an aptitude for science. Level-headed and pragmatic, she can be seen as the voice of reason for the series. Additionally, Kouhai-chan describes her as "nit-picky and argumentative".Manga, Vol 4, Chapter 32, Page 8
She is subtilty hostile towards men whom she believes to have lustful intentions towards her and her female friends. However, she is seen to be a good judge of character, as she was able to detect Senpai's good-hearted intentions toward Kouhai. 
==History==
====== Webcomic ======
In Rikei's first appearance, we see her experimenting with a "chest fat-burning" serum. However, the serum starts overreacting and spills over, burning away her clothes instead. Later on, Rikei is seen tutoring a younger unnamed male student for his upcoming college entrance exams. The student asks Rikei if he can grope her breasts as a reward for passing the exams under her tutelage. While initially hesitant, she appears to have considered the offer.
After failing the first entrance exam, Rikei's student becomes depressed and walks away in shame. Rikei, realizing there's a second chance for success while simultaneously feeling guilty for his failure, offers him an "upgrade" to the initial offer (groping her breasts without clothes in between) if he passes the second entrance exam. Time passes and the young man finally passes the exams. He then looks toward Rikei with full intention to claim his "reward", but then hesitates when he sees her crying tears of joy at his success.
From then on, Rikei made a few more appearances depicting her growing relationship with her student, including: having studying sessions together in college, going to the beach, and inviting him over to her apartment on his coming of age day (the day in which you turn 20 in Japan).
Sometime after the exams, Rikei is seen hanging out with a drunken Kouhai at a bar. While keeping Kouhai under control, Rikei comments that "even though she became a working adult, she hasn't changed much at all, huh?". It is later revealed that Rikei and Kouhai are long time friends, as their friendship dates back to their first years in college. Back then, Rikei would constantly be protecting Kouhai from persistent men looking for one night stands.
Later, Kouhai introduces Rikei to her Senpai at a cultural festival. At first, Rikei disproved of Senpai, thinking that he only had lustful feelings toward Kouhai. But is later seen joyfully sharing stories with him about Kouhai's drunken escapades (at Kouhai's expense). At that point, all three of them became really good friends, and ever since then have had regular hangout sessions.
====== Anime ======
Rikei is briefly seen conversing with Kouhai over text regarding Kouhai's bathing suit choices, all of which Rikei swiftly rejects for being too skimpy.
