She is first introduced to us as Nippachi (apparently because she always gets a 28/100 in tests and is always grinning). Upon hearing this Maria stated that Tomoyo was looking down on the very girls that called her Nippachi. This aggravated those girls a lot, and shocked Tomoyo (indicating in a way that Maria was correct). Later, the other girls in the class made Tomoyo give an invitation to Maria for a fake welcome party for herself. The reality was that the girls in the class were going to make Tomoyo drink a lot of alcohol and then say that Maria made her do so. They supposed this would work because they already convinced Tomoyo to lie and say that Maria beat her up earlier. Upon receiving the invite, Maria, who was already aware that no good would come to the party stated that “I think, no matter how much filth you show, I need to go”. Hearing this Tomoyo pushed Maria down the stairs, insisting that she was not filthy like Maria. Tomoyo ended up crying. Then Kanda Yuusuke showed up at the party with Tomoyo. He smoothed out the whole situation. The next day, Tomoyo appeared in school with a cast around her legs and crutches. Then the other girls insisted that Maria pushed her, which was not true. The other girls in the class asked Maria to be Tomoyo's replacement; Maria abruptly refused, saying that she could not just go around smiling at everyone, and that she could only be herself. It was very soon after that the class discovered that the cast was fake. They then began to call Nippachi a liar, even though Nippachi insisted that she fell down the stairs that morning, which was later proven wrong. Tomoyo did not show up to school for the next week. This was later considered a problem, so the class and teacher told Maria to bring Tomoyo back to school. She and Kanda went to her house together. They spoke to her normally and then left. The following day, Maria went to Tomoyo's house before school and told her to come to school with her. At school, Nippachi defended Maria and also put an end to the other students and the teacher calling her Nippachi. This begins the friendship between the two of them.
