After Mine tells Tatsumi of her past, and her motivations for joining Night Raid, they are ambushed by the remaining guard. Mine snipes the main target dead despite him being surrounded by innocent people, to Tatsumi's surprise, while the rest of the group kill most of the guards. Later, Night Raid is sent on a mission to assassinate one of the prime minister's relatives and his guards. Shortly afterward, the two witness public executions, and Tatsumi learns of Mine's determination to survive.

The two then go around shopping in the capital, and Tatsumi is angered to learn that was supposed to be his training. Later, he goes to wake up Mine, which leads to an embarrassing situation after he walks in on her changing. While dispatching an enemy force trying to invade their base, Tatsumi learns of Bulat's Imperial Arm, Demon Armor: Incursio. Tatsumi is then informed by Najenda that he will be working with Mine for now, while in the distance Mine feels a chill, questioning why she felt it. Leone and Akame successfully take out one of them, and Tatsumi, with a little bit of struggle, takes out the other one on his own, earning their trust and becoming an official member of Night Raid after Akame's inspection of seeing any bodily injuries. Their goal was to take out two individuals who were high up in the government.

Before Tatsumi could be excepted into Night Raid, he had to help them with a specific assassination to prove his skill to them. While he didn't think much of Bulat, Sheele, Mine, Najenda, or Lubbock either way, he still got flustered around Leone all the time, and began to dislike Akame at first, both because of her strange attitude toward him, and because she tried to kill him the previous night. Tatsumi is taken to the Night Raid's secret hideout by Leone, in which he's introduced to the rest of the members of Night Raid-Bulat, Sheele, Mine, Najenda, Lubbock, and of course Akame, the latter of which who tried to kill him the previous night-and instantly formed distinct relationships with each one of them.
