Third person POV
Reina and Gen spent the rest of the day researching for the cure on the zombie virus and training for their counterattack against the zombies. At night, after dinner, like they had promised, both of them took their second dosage of their 4 medicines for their mental illnesses.
Then, later at 9:55 p.m., the two of them slept together in Reina's room. The main reason why is that Gen would comfort Reina in his trauma. Gen did so as if he was Reina's father. Reina was now sleeping in peace while being hugged by Gen.
A few days had passed, and Reina is now ready to go on assault operations against the zombies in the outside world. So, Gen assigned him to Nato's squad in the city of Minato within the Tokyo Metropolitan Area while he was still researching and working on the possible cure. Reina accepted it with determination on his eyes, wanting to do something for him in order to alleviate his guilt. And so, in the chaotic streets of Minato city, Reina, Nato, and Nato's squad are now attacking the zombies, who were trying to break into an abandoned café that was being barricaded by some survivors. Nato and his squads are armed with guns, flashbang grenades, and riot police shields while Reina was armed with his katana. Reina slain most of the zombies with skills like an anime character. The zombies are no match for their combined skills in combat.
After some time, the zombies in that area were killed, and Reina and his group managed to get the survivors out of the café. Those survivors were then led by Nato and his squad to a safer place in one of the city's subway stations. Reina, meanwhile, continues to scour the surrounding areas with 2 of Nato's squad soldiers. At this point, he got along with those soldiers and others in Nato's squad very fast, and they understood his pain of his trauma resulted from his past actions on their organization leader.
