Nah. In the anime when talking with the students the teacher things that Sophia and Shiro (and i think a few others) are dead but never confirmed about Sophia and Shiro, just assumed because their names got grayed out, so I imagine Sophia ends up finding a way to block the skill and Shiro was grayed because she is no longer within the system

Nah, in this universe the elves are very evil. They believe themselves better than everyone just for existing (not too uncommon but its on the 'you should either kneel or get out of my sight before i kill you' level) and are the reason the world is dying because most know what Potimas is doing and don't see a problem. I also don't know if you watched the anime or not but in it it shows how bad the kidnapping was because of the moronic teacher

That bow could be an amazing bargaining chip. I think the #1 guy uses a bow so I imagine that he will get the item Seon needs and have the arrow and they will trade or he will get the arrow and owe Seon a major favor of some kind in exchange

Isn't his mana already on par with the goddess? Why tf would he want more since he already has such difficulty just keeping what he has suppressed so the goddess and demons don't find him?

He said that when it appears the other monsters scatter, so they are probably waiting for it to show up and flee 'under its shadow' but I imagine it will still notice them, MC will try to keep it occupied and the girls will gain what they need to get RfT right before the gigant kills everyone again

Is homie ever gunna get some or any of the girls going to make an actual move? Seems kinda dumb if they made it out to be women are worse than men on earth but so far no one has done anything besides dirty thoughts
