Blue Lock chapter 306, titled Hello, saw Seishiro Nagi become desperate to return to Blue Lock. Hence, he camped outside the facility, hoping for someone to come outside and give him a second opportunity to fight.
After no one came to speak to him, Nagi realized that he could have simply called one of the Blue Lock survivors and had them help him connect to Ego Jinpachi.
