Episode 29

Reaper Time, Part 1 is the twenty-ninth episode of the Assassination Classroom anime and the seventh episode of Season 2. It first premiered in Japan on 18 February 2016.

Summary
When Irina is kidnapped and held hostage by the legendary assassin known as the God of Death ("Reaper" in Funimation subtitles), Class 3-E attempts to rescue her without the help of Korosensei and Karasuma. But the God of Death's skills may be far too outmatched for the students to handle.

Plot
Toka Yada, Hinano Kurahashi and Hinata Okano discuss with Irina about their new PE uniforms from the government. Irina states that she originally wanted the girls' uniforms to be more revealing but compromised with Karasuma's vision, to which the girls are grateful for. Irina then chastises Karasuma for not giving Irina a present as she walks away. The girls remember that October 10 (four days previously) had been Irina's birthday.

In the staff room, Irina privately thinks to herself about not receiving anything from Karasuma, nor that she cannot contact Lovro since the summer holidays. Megu Kataoka and a few of the girls take Irina outside to ostensibly learn more French. Eavesdropping out of the window are Okajima and Maehara, who radio Nagisa's group at the town to buy a present. As they wonder what to get someone who has almost everything, the flower shop man who had witnessed accident two weeks ago approaches them. Confirming their intentions to buy a present, the flower shop man makes a convincing sales pitch for a bouquet of roses. The students buy them.

Nagisa's group returns to the mountain classroom and convinces Karasuma to take the flowers to present to Irina. With that accomplished the group of students who're busy pampering Irina suddenly leave, much to her confusion and chagrin. Returning to the staff room however, she finds Karasuma who wishes her a happy birthday and presents her with the bouquet of flowers. Initially speechless, Irina thanks him. Karasuma then states that it will be the only time to mark such an occasion as either the world ends or the mission is successful. At this Irina realises she has been set up, walks over to the window and finds the class eavesdropping underneath (and a spying Korosensei from above). She hopes that the class ad fun stringing a professional assassin along as she realises that their relationship is strictly a business one. She rejects the flowers and storms out of the classroom. The students accuse Karasuma of being cold and not noticing Irina's feelings for him. He answers that he did notice but states that Irina's blade has been blunted by romance and therefore not suited for their mission. At the school carpark, Irina contemplates leaving the mission as a figure approaches behind her.

Three days have passed and Irina had not been seen since her storming out. The students worry for her wellbeing and unable to contact her as Korosensei leaves for a soccer match in Brazil. Afterwards, the flower shop man casually walks in as though blended with the environment, with the students only realising his presence after they speak to him. The man introduces himself as the God of Death and tells Ritsu to open the image he had just sent to the AI. The image reveals Irina tied up and gagged. The assassin demands that the entire class go to the location he will specify without any word to their teachers, or else he will send each of them a piece of Irina and take one of them hostage in her place. Terasaka threatens him but the God of Death instantly leaves in a flash, leaving behind a map and a note telling them to go the location on the map at 6pm.

The class arrive at the location wearing the new PE gear. With nothing standing out according to Itona's recon drone, Sumire Hara tells Ritsu to tell Korosensei of the situation if they're not back by midnight before the class enter the complex. Arriving in a big room, the God of Death greets them via camera before activating his trap. After seeing Irina tied up, the class try to find a way to escape. Okajima keeps the God of Death distracted by talking to him as Mimura finds a hollowed spot on the wall. Takebayashi sets explosives while Okuda throws down a smoke bomb to cover the class's escape. Their efforts though pleases the assassin, getting a chance to warm up until Korosensei arrives. At the same time the class split into two groups, one led by Isogai to potentially fight the God of Death and another led by Kataoka to rescue Irina. Meanwhile Korosensei is enjoying himself in Brazil but his innocent remark of 7 to 1 unwittingly angers the locals. His failed attempts to contact various students however make him worry as his simultaneous dodging skills reverses the locals' attitudes towards him.

The battle group try to strategise with the mobile Ritsu. Unfortunately they realise from her lazy behaviour the AI had been hacked into. At that moment the God of Death approaches in a shrouded matter with no one unable to make him out. Muramatsu and Yoshida charge at him but the assassin takes them out with ease with his close combat skills. Next moment he appears among the group and kicks Kayano in the ribs. Although the cracking sound was emitted by her PE suit to withstand the impact, the assassin's emotionless statement thinking the girl's ribs were so brittle angers Nagisa. He walks up to the assassin with a taser in hand ready to perform the clap stun technique. However the God of Death does it first, stunning Nagisa into paralysis. The assassin instantly takes out the rest of the battle group who are vastly outmatched by his speed and explains to Nagisa about the wavelength of a human's consciousness, and striking at its peak before the boy falls unconscious. Meanwhile the rescue squad find Irina and untie her. However Irina betrays the group and using various tricks to incapacitate most of the group much to their shock. While Terasaka prepares to fight her and the God of Death who had just arrived, Itona instead opts to surrender, hoping to win another day.

The class is soon imprisoned in a large cell, Nagisa still dazed out from the clap stun technique. Karma asks whether the assassin's fight with Korosensei will go according to plan though he answers that no matter how poor the intel he will still get results. Looking at his monitor however he finds Karasuma outside the complex with Korosensei acting like a dog to track the students' scent.

Trivia

 * Korosensei's remark of 7 to 1 is in reference to the 2014 FIFA World Cup semi-final between Germany and Brazil. Brazil's humiliating loss is also referenced by the locals who were painfully reminded of the outcome hence why they attacked Korosensei.
 * The anime has the class split into two groups - a combat group and a rescue squad. In the manga a third group was also created to recon the area.
