Daihaseisai or Daihasei Festival (大覇星祭 (だいはせいさい) Daihaseisai ?, lit. "Grand Champion Star Festival") is an annual city-wide interschool sporting competition that takes place September 19 through September 25 in Academy City. It is a major milestone in the Toaru Majutsu no index story, with currently two story arcs occuring during the events of the festival.
Daihaseisai is a famous Academy City competition where students from various schools compete against other schools in numerous athletic events. During the week of the competition, Academy City is packed with tourists and the students' parents. The city-wide sports meet is broadcast worldwide, with ratings comparable to even the World Cup. Because of this, it makes Daihaseisai an inherently viable political tool for Academy City.
During this week, people are usually prohibited from entering school premises, in order to avoid outsiders from seeing the power development facilities unique to Academy City schools. Sports grounds also tend to be heavily guarded in order to prevent people from stealing DNA maps of high level espers.
Participants are encouraged to use their abilities during the matches, which is why the high-class schools like Tokiwadai Middle School excel during it. In some cases where events are held in the general public, abilities past a certain threshold, specifically the Level 5s, are forbidden in case they harm people, like when Mikoto was in the 'borrowing-items race' she could not use her powers as it was too dangerous, even if she restrains herself. These restrictions don't apply in other matches where it is only school versus school. Schools are ranked according to their scores based on their wins and losses, and the highest one becomes the champion of Daihaseisai, though only the top 5 schools of Academy City are the ones that are truly competing for the championship. Each school divides its own students to a red and white team, with the number of wins each colored team gets, the points earned would be added on to the school's score.
Although it is a large-scale sporting event, not all the students would be bounded by the events all the time. They just need to follow the rule of reaching the area in the specific time, and any time other than that was free time for them. Schools are even allowed to set up stores to get some earnings like the management or home economics schools that Tsuchimikado Maika is in.
According to details in a pamphlet given to students, the main purpose of the festival is to observe large-scale interference between Espers. The Daihaseisai is also used by people to evaluate the esper development program of each school, and thus affects the budget of each school receives.
Preparations for the Daihaseisai are performed weeks in advance, with the Daihaseisai Management Committee, composed of students, doing the work and preparation, such the layout out for the roads to prepare for the oncoming traffic, as well as refereeing competitions. They are separated by the levels of education. For example, Fukiyose Seiri is part of the High School Division of the committee. Academy City Board of Directors are able to contact this committee as well and can order them to do specific things. Committee members are not exempted from taking part in matches however in spite of their duties, as such they had to arrange their work schedule such that it didn't affect their own matches.
Schools prepare well in advance as well, training for the upcoming competitions. An example of this would be Tokiwadai Middle School, more so during the current year of the timeline after they came second to Nagatenjouki Academy last year, setting up a school-wide P.E. lessons for the Daihaseisai. For the festival, both Judgment and Anti-Skill like Uiharu Kazari and Yomikawa Aiho respectively are deployed to keep peace and order and aid outsiders.
For transportation, other than the rerouting of traffic flow by the Committee, the Daihaseisai marks the widespread use of automated buses in restricted conditions in spite of the difficulty of using them, while ordinary vehicles are banned, though taxis, delivery trucks, and ambulances and likely other emergency vehicles are still allowed.
Nagatenjouki Academy was the previous year's Daihaseisai champion with Tokiwadai Middle School at second place. The current year's Daihaseisai has both schools retain the previous year's ranking.

Though tossing the ball toward the balloon is normally applied, the rules are flexible enough to allow a competitor to hold the ball to puncture the balloon. When a balloon is punctured, the competitor is removed from the game. The team with the most players remaining in the game after the designated time ends is declared the winner. The grounds for this competition are vast, encompassing the starting area as well as alleys and roads, allowing for competitors to hide or take refuge. However, going out of bounds such as going into stores or unsigned roads leads to disqualification.

Toaru Majutsu no IndexEdit
- Main article: Daihasei Festival Arc (Index)
Daihaseisai takes place on September 19 during volumes 9 and 10. In the volume 9 prologue, Touma makes a bet with Mikoto that his school will beat hers, which leads into the premise of volume 12. During the event, Touma doesn't actually participate much, as the majority the 19th is spent chasing after Oriana Thompson along with Tsuchimikado Motoharu and Stiyl Magnus. While they pursue Oriana, they try to learn the real goal of Oriana and Lidvia Lorenzetti. Along the way, Himegami Aisa is hospitalized due to a misjudgment by Oriana, Fukiyose Seiri is also hospitalized by touching one of Oriana's traps, and Motoharu is injured several times. After pursuing Oriana until dusk, Touma manages to defeat her, but it turns out his efforts were futile, as not only did Oriana not have the relic to thwart their plan, the magicians' plan wasn't going to succeed since the beginning. In the end, Touma is hospitalized from the injured caused by Oriana, and in the next day, he was alright, but got into all sorts of unfortunate events for the rest of Daihaseisai, finally winning first prize in a lucky number contest on the last day of Daihaseisai, which earned him a trip for two to Italy.
Toaru Kagaku no RailgunEdit
- Main article: Daihasei Festival Arc (Railgun)
The Daihaseisai in Toaru Kagaku no Railgun takes place at the same as the one Toaru Majutsu no Index, though it extends to the second day unlike the one in Toaru Majutsu no Index. Moreover, though the Daihaseisai still serves as a backdrop for much of the events of the arc, there is more focus on the games early in the arc, where Misaka Mikoto herself participates.
