Toaru Majutsu no Index Wiki

Strange Coincidence (奇縁 Kien?) is the 19th episode of Toaru Kagaku no Railgun T. It was broadcast on August 14th 2020. The episode was directed by Akari Ranzaki, the screenplay written by Yasukawa Shogo, and storyboarded by Takada Kouichi.

Upon stumbling upon information that the fish can give a beautiful figure, Saten quickly bought cans of mackerel. But, because she took the last two cans up for sale, a girl named Frenda missed out on the sale and collapsed on her shopping cart, bringing Saten to an awkward situation involving the girl following her around.

Frenda, ever the lover of canned mackerel, decided to split one can open, only to end up carelessly wasting the can, bringing the girl to tears. Although partly annoyed at the situation, Saten somehow cannot leave the girl behind, so she invited her for a meal at her home. Even with Frenda's tendency to act and talk at her own pace, Saten had an enjoyable time with her. Afterwards, the two exchanged contacts in a messaging app, and will once more meet each other at a certain incident...


Kuroko is assisted by Mikoto as she works on a report related to the Treasure Hunter App she and Uiharu investigated previously. Although she appreciates the gesture, Kuroko advises Mikoto to refrain from meddling with Judgment work this time, especially as things become more hectic on Kuroko's end. Meanwhile, Mikoto decides to take a break from using Indian Poker cards for the meantime. Kuroko agrees to her decision, revealing that she also had a bad experience with the cards.

At Sakugawa Middle School, Saten's plans to gather her friends are dashed as Uiharu was assigned on patrol duty as a result of the incidents revealed by the Treasure Hunter App. Saten instead goes to the supermarket, where she is lucky enough to pick up the last two cans of mackerel in stock. Frenda, who missed out on the mackerel sale, becomes desperate in getting Saten's cans of mackerel to the point of tackling her once and later following her outside. Saten rejects Frenda's attempts to trade the mackerel for "dolls" and "fireworks" and eventually relents to the incessant pleas to have a can. But, to Saten's chagrin, Frenda uses a kind of explosive tape to open the can, resulting in its contents being wasted. Although slowly losing her patience towards the girl who wasted a can of mackerel, Saten decides to invite Frenda for dinner at her home.

Frenda is shocked to discover that Saten prepared mackerel curry for the two of them, as she prefers eating mackerel on its own. But, she eventually found herself enjoying the taste of the dish Saten prepared. After the hearty dinner, Frenda promises to treat Saten next time, and she exchanges contact details with her on the Speech Bubble social messaging app. Although she saw Frenda as the type that doesn't hold back, Saten somehow enjoyed their night together.

The next day, Uiharu once again parts ways with Saten for Judgment duties. Meanwhile, Saten would spend the next few days chatting with her new friend about the mackerel fad dying out in a day, the experiences they have with their friends, and their moments using Indian Poker. One day, Saten visits a roadside Indian Poker trader for any new cards up for sale, and the trader recommends cards for American cracker, coin stacking and for expert handling of chopsticks. Unknown to Saten, her Speech Bubble message is intercepted by a boy wearing goggles, who then relayed this information to a girl in the dress. The girl in the dress is aware that scientists use Indian Poker cards to store information that's not archivable otherwise as a form of insurance, and the card for "expert handling of chopsticks" actually refers to the operation of a device called Tweezers. Although the boy with the goggles is unsure of the veracity of the information he intercepted, he decides to eliminate any false flags in his search.

Saten purchased the card for "expert handling of chopsticks" from the trader the next day, and is excited to use it. But, she finds herself becoming an abduction victim by two thugs and others in two getaway vehicles. Frenda witnesses the crime taking place and, wanting to repay her kindness, decides to call Hamazura Shiage for backup. With the help of his own getaway vehicle, the girl is able to catch up to the abductors and stop their escape.

Meanwhile, the boy wearing goggles infiltrates a facility on his own, using his ability to turn invisible, open secure rooms and create a copy of an Indian Poker card stored inside by using a blank card and the fragrance components of the original. Although successful in his own mission, the thugs (which work under his faction) are intercepted and neutralized by "someone using explosive dolls". Eventually, Saten is set free by Frenda, forcing the boy wearing goggles to send out another operative to the mission.

At Private Shidarezakura Academy, a girl named Yumiya Rakko is invited by two of her schoolmates for an adventure outside of the School Garden. She is glad to be invited, but the call from the boy wearing goggles compels her to turn down the offer. While she meticulously investigates the scene of the clash earlier, Rakko vents her frustrations at the girls who interrupted her potential moment to become famous in her campus.

Saten and Frenda escape unharmed, with Saten only losing her phone and the Indian Poker card she just bought in the abduction. Frenda assures Saten that things are fine and decides to bring her to the nearby supermarket to buy more cans of mackerel. They are unaware that Rakko is on the hunt, using the remnants of blood in Frenda's clothes to locate them before going for an attack, marking Frenda as her prey.

  • This episode confirms that the first day Saten and Frenda met is at September 28th of the current year.


  • When Mikoto praises Kuroko for her efforts as a Judgment member, a scene from Railgun T Episode 16 where she saves a student was used as flashback. The Treasure Hunter App was also referenced.[5]
  • When Mikoto remembers her bad experience with Indian Poker, the scene where she and Misaki beat up BLAU and his fans from Railgun T Episode 16 is used as flashback. Kuroko also referenced having been traumatized from Mikoto's response to her monologue when the latter experienced Indian Poker for the first time from the same episode.[5]
  • This episode coincides with Railgun T Episode 17, where all incidents involving the Treasure Hunter App are happening at the same time. The beginning of this episode is also the same day Kuroko and Shaei met.[5][6]
  • This episode references Frenda's later distaste of canned mackerel and her desire to eat curry as featured in Index Light Novel Volume 15, which was adapted to Index III Episode 4.[7][8]

Cultural References

  • The brand on one of the billboards is Posiqlo, which is a parody of Uniqlo, a Japanese clothing retailer.
  • Frenda's reaction to mackerel curry is a mirror of a character from JoJo Part 4, chapter 39 of the manga, in which Okuyasu visited an Italian restaurant. He first proclaims that the food won't taste good, immediately followed by a large exclamation of him finding it delicious, after which he states how the two ingredients blend amazingly together, enhance one another, and achieve a perfect harmony. This is repeated here in the episode with Frenda stating she thinks the mackerel curry won't taste good, loudly finding it delicious, and then stating the two tastes pair well together, draw out each other's flavors even more, and achieve a synergy.
  • Frenda utters "Deilig" when she is eating mackerel curry and "Ha det bra" to Saten when she was about to leave the dormitory. The former is Norwegian meaning "delicious". The latter is Swedish or Norwegian language meaning "Good bye".[11] Thus it appears that Frenda originates from Northern Europe, or has profound connection with there. The latter is also the title of the next episode.
  • Orange Computer is a parody of Apple, a US technology company.
  • FUKIDASHI (Japanese for speech bubble) is a parody of Line, a Korean messaging app, with the logo being a speech bubble.
  • The car that Hamazura drives in this episode is based on the BMW Mini Hatch, also known as Mini Cooper, specifically the third generation S model, in which the steering wheel is on the left side of the car.

Differences in Adaptation

  • The scene at the beginning of the episode, where Mikoto praised Kuroko for her efforts as Judgment member is anime-original.
  • Two separate scenes with Saten and Uiharu together, when the latter is busy with her Judgment duties concerning incidents related to the Treasure Hunt App are anime-original.

Animation Trivia

  • The mackerel can is rendered in CGI after Frenda blew it up to open it.
  • Most people in the background are rendered in CGI.
