The light

'Why Z0a?! I don't want to die yet! Why can't we just merge or something?! Come on, don't be so reckless!'

Why Neon found Z0a to be reckless is because Z0a was ready to sacrifice herself along with Neon as food for Alissa. Entering the consciousness of Alissa, she was willing, and the moment she arrived in the plane of consciousness, she even called for Alissa to take over her and consume the soul of hers.

"Huh? Z0a? Why are you here? I heard you screaming earlier outside of my consciousness… Did something happen?"

Within the mind plane of Alissa, the figure of Alissa faded in in front of Z0a after Z0a had yelled out her name. Apparently, it seems that Alissa who is only a soul core in reality, is only able to see her own mental world. However, although she can not see, she can still hear what is going on outside in reality. Because of this, she was updated of what has been happening as of late, and knew pretty much a gist of it all.
