Kael got confused hearing Rias's words, but Alpha quickly filled in the details for him. She had been deciphering the information left behind by the Storm Dragon and had gained something new.
[The Astral Projection is just a projection of your Soul Body in the Astral World. There's a connection between the two, so using the Astral Projection of the other party, you can transfer some information to them directly through the Astral World.]
'Yeah, but I can't access the Astral World yet, so how am I supposed to do that?'
[But you are very close to the C-Rank, which means you can access the Astral Vision, which lets you sense the effects the Astral World has on the Physical World. You can use the connection between the Soul Body and the Astral Projection to locate it and transfer the information.]
'Does that mean I can also sense if someone near me is extracting Mana from the Astral World?'
[Yes. It is one of the advantages of achieving the C-Rank.]
'Nice. Can you teach me that?'
