Erasa (イレーザ) is one of the Orange Star High School students who are from Satan City. Normally, she is a very talkative person and she spends a lot of time with Videl, her best friend, along with Gohan and Sharpner. She appeared a frequently during Dragon Ball Z and makes a small cameo appearance in Dragon Ball Super before the Resurrection ‘F’ Saga 
Erasa is a blonde girl with a lined green tube top and blue jeans. She is in Gohan's class at Orange Star High School. She is very sweet and cheerful. Erasa becomes good friends with both Videl and Gohan. Naturally extroverted, she did not hesitate on flirting with Gohan.
Her and Sharpner's names are based on school supplies, with her name being derived from the word eraser.
Dragon Ball Z
It is she who asks Gohan to sit near her during class and to go and study at his house. She is also the one who introduces to Gohan the fact that Videl is Mr. Satan's daughter and, ironically, how Gohan should thank Videl's dad that they are still alive. This is ironic because she is talking to the actual savior of the Earth from Cell, Gohan.
Later, Erasa comes to Papaya Island with Sharpner to watch the 25th World Martial Arts Tournament and was very confident that Videl would win against Spopovich. However, after she was brutally defeated, Erasa was very horrified along with the rest of the crowd.
When Gohan's turn came, he accidentally let his Great Saiyaman disguise fall off in a fury while watching Videl's brutal defeat, and while Sharpner was surprised at this revelation, Erasa merely thought that Gohan was using the name because he was shy. Then she and the crowd shouted out cheering for him, despite thinking he does not know martial arts. However, Erasa was speechless and surprised when she discovers that Gohan was the "Golden Fighter".
She was presumably killed along with the rest of the people of Earth when Super Buu uses his Genocide Blast. She is later wished back with the Dragon Balls, and is seen giving up energy for Goku's Super Spirit Bomb along with Sharpner and the others at the school, all cheering for Mr. Satan, whom they thought they were giving their energy to. She appears briefly at the beginning of Dragon Ball Z: Wrath of the Dragon, but has no lines.
Dragon Ball Super
Resurrection F Saga
A few years later into Dragon Ball Super, Erasa graduated from Orange Star High School. Much of her life after this is unknown, but prior to the 'Resurrection of F Saga' she is shown to work at the Penguin Kio steak house. She along the other employees often serve the Brief family and served Whis, courtesy of Bulma.
