Neza had thought hard enough about joining Rein, the only reason why he was holding back was probably because of his pride, all consequences whatsoever has been ascertained by the eight members that make up the main body of commanders in the party.
"....."
News of the Ironsmith, Amazons, Chaosblade and Magicmanes quickly reach Neza. He was now to make a decision whether to join or to stay out of it. He understood this was a sensitive matter that needed to be decided not based on emotions but judged carefully on how it would benefit the party itself, eight students, each of them with their individual standing behind them, sat around Neza awaiting his decision.
If Neza decided to accept the offer, it would mean he was acknowledging Rein maybe not acknowledging everything about him, but he wouldn't be able to kill him if he wanted to, right now that was what he desired most: to take him out of the way and make him realise he should've stayed his place.
