Tamashi was a tad aggravated when Fenrir wanted him to train despite having been shot multiple times. Sure he could handle a lot more damage than the average person but a couple days to recover isn't a lot to ask. Especially when you have broken ribs. Fenrir might think that you should push through the pain no matter what but Tamashi knows very well that pushing yourself when wounded would only result in more damage.

Tamashi reluctantly went to bed to try and recover for training the next day. When he slept he had a dream. It was a dream of hell. He dreamed about the demons he forced to come to earth. How he had enslaved them for his own ends. What he felt was not a regret for his actions but an anger inside that he was forced to release them back to their home without having achieved his end goal. Then he dreamed about his fight with King. He repeatedly relived the moment where he thought he had one the fight and then his own team mate shot him in the back. In his sleep he called out in pain as his flesh was pierced by the bullets of his memory. 

While he slept his ribs healed. While they weren't fully healed by the time he was awake they were in much better condition than they were before he went to sleep. When Tamashi awoke he got dressed and grabbed his sword. He would have to skip breakfast as he had already consumed all the blood he had stored in his room. He would have to make a point of acquiring more later. He headed down to the training room and looked around at the other team mates who had arrived. His eyes had bags indicated his sleep was not a restful one. He began to seriously consider the benefit of being part of the team. He had done much better solo in the past. Seeing how he was still recovering from his wounds to the upper body Tamashi decided to begin on the treadmill.
