Despite trying out different tactics, Iori hasn't been able to get much information out of Ren. Still, she hasn't given up. She must be patient. The tongue has no bone. Thus, it can often slip out the words that the mind tries its best to keep inside.
When they arrive at the Kamiyama Villa, the guard lets them inside without any question. Ren goes straight to the kitchen. He's tired of the girl's questions. Her efforts to make him speak about Nina and the assassins didn't go unnoticed. If she hasn't been Takeshi's friend, he would have lost his temper countless times.
He looks at his clothes. He has to change before he destroys the sanctity of the holy kitchen. He needs to eat a lot to not feel sad anymore. Perhaps, he will continue to feel sad even after eating. He wants to watch anime or read manga, but he ends up thinking about Nina. He has to prepare for her funeral.
