As there are many intense action scenes, the cast have suffered small injuries such as scratches, cuts and bruises. Oguri related that there was once when he was punched really hard by Araki during a practice session and joked that she had the guts to continue raining punches on the lead actor's face which led the latter to apologise for that. Araki said that she had to deliver her punches for real at Oguri's request or else it wouldn't look convincing on screen and she had no recollection that she had punched him.
Oguri and Nishijima who began action scene training more than 18 months ago, said that they had requested the producer to arrange for strong opponents in the drama. To their surprise, they got more than what they bargained for and were subjected to strong counterattacks such as shoulder tackles and elbow bats. The actors who are working together for the first time, were asked about their weak points. Nishijima said that Oguri is too absorbed in his work that he even goes for training during the filming off-days and learn how to use the gun during the filming breaks. On the other hand, Oguri said that Nishijima can't do without sugar in his body and would be weak like Anpanman with his face wet.
