My theory is still that his dad is a 9th dimensional god of let’s say chaos. One of the creator gods in Greek mythology. Chaos represents progress but stagnation, ******* but oppression, order but disorder, creation but destruction, lastly life but death. Chaos is literally everything but nothing at the same time. Imma say that his dad a bunch of gods United to seal him away around the beginning of vahn mammas pregnancy. The dream goddess is actually his sister but only recently found out.
"Age: 14 (Earth), 16 (Danmachi)" Is he not 14 when he first arrives in Danmachi? Also he hasn't even been there for 1 year yet, right? Though he stayed 3 years in the Soul Room place, it was mentioned that that place is "timeless" or something, so he should still be 14. Or is this a hint that when he is 16 he will move towards the next world? ^^
