Just then, two twin hitmen appears behind Kyoko and Haru and Birds introduces them as the Bloody Twins, two serial killers.

Gokudera angrily charges at him but Birds threatens to kill the girls if he attacks him, forcing Gokudera to let go of him.
Birds orders the others to beat up Tsuna until he sees blood, threatening to set the girls' hairs on fire if they refuse. Forced to comply, Tsuna shouts out to Gokudera and Yamamoto to do it but the two refuses.

Birds then orders the group to stab Tsuna with his knife, promising to let the girls go if they comply. Everyone begins to argue, causing Birds to order the Bloody Twins to pour some Sulfuric Acid on the girls. As the twins follows his command, Tsuna tells everyone to stab him, not wanting the girls to face any kind of cruelty. Birds is disappointed about not seeing the girls in pain but thinks that his job is done since a scratch from his poison-coated knife is enough to kill Tsuna. Gokudera and Yamamoto refuse to stab Tsuna but Bianchi tells them that she would do it, saying that she'll immediately call an ambulance. Tsuna refuses her offer, saying that he'll stab himself, thinking that since Gokudera and Yamamoto covered for him it's the least he can do.
