School Trip Arc
Mandalei first appears when she introduces herself along with Pixiebob to Class 1-A. Mandalei explains to Class 1-A that they will be staying at the base of a mountain which is a part of their domain; they have three hours to reach the base of the mountain using their Quirks as they please and those who don’t arrive there by 12:30 pm won’t be served lunch. Soon, Class 1-A realize that they have already arrived at their destination and their training camp has already begun with the Pussycats being their supervisors. Some of Class 1-A try to leave, but Pixiebob uses her Quirk to create a landslide of dirt that causes Class 1-A to fall into a forest called Forest of Magic Beasts, which they must traverse to reach their destination.

Mandalei notes that the training camp he has organized has been well thought out; Shouta attributes it to the fact that the increased number of villains has forced the first years to take the accelerated year course (usually reserved for second years) so that they have the skills and knowledge to fend for themselves. Shouta lets the Pussycats handle the beginning portion of Class 1-A's training camp and leaves. Mandalei tells Kouta that they are heading back.

Later that day at 5:20 PM after Class 1-A arrive at the facility, Izuku asks about the boy, Kouta and wonders if one of them is his mother. Mandalei explains to Izuku that Kouta is her nephew and asks him to say hello to Class 1-A.

Later that evening, Izuku saves Kouta from his fall and brongs him to Mandalei. In the office, Mandalei thanks Izuku for being there to help him. Izuku notes that Kouta doesn’t like the concept of Heroes and explains that he along with many others grew up in an environment where they wanted to become Heroes; Izuku is surprised that Kouta has a jaded view on Heroes. Mandalei explains that there are people in the world who don’t like Heroes and if Kouta had a normal upbringing, then he would have grown up to idolize Heroes as well. Pixiebob arrives and tells Izuku that Kouta’s parents (who are Mandalei’s cousins) were once Heroes and explains Kouta's backstory. Mandalei tends to Kouta while Pixiebob explains to Izuku about Kouta's history.
