(I'm not sure if you realise this but the way Nero refers to people without honorific is only used between close friends otherwise its rude. bsically he's being rude to people. Its not exactly that he's trying to be rude but he just doesn't care for formalities.)

Tessai nodded at Hana since Urahara was currently occupied trying to pry his head from the wall.

"Are you going out Zant-san?" Tessai asked.

Nero leaned back as he popped a piece of crab sushi into his mouth as he thought about what he was going to do. He needed to train now tht he was back at Urahara's. The mans training area was good for training at high power levels since it hid any Reiatsu that was inside it. Nero knew that he had more power hidden within him beyond his Resureccion but he couldn't access it right now. In order to do that he needed to train at full power.

"I'm going to train." He told the large man after swallowing "I can get stronger then I am now."
