Any one else think it's strange how Eculid lucifige was just able to make a second boosted gear out of thin air. I haven't fully read Volume 16 yet so i apolgize if its wrong, the only reason i know this is beacuuse i read it on this sitre.

It Seems like he would have had to atlest studied Issei or a past Sekiryuutei in order to do it, just like when Azael studied Vali and Divene Dividing to make Down Fall Dragon Spear.

So maybe something happen in Issei's past which alowed Eculid to do it and at the same tim cause Irina to move away when they were younger, all of which might be explained in her volume, which i believe is going to be Volume 19.

Issei may alos have his own seperate volume to deal with his past, as his parents do seem to have secrets and were totslly cool with over half a dozn teenage girls comeing to live with their so ant that their house was turned into a 6 story mini-mansion over night while they slept in it.
