Danmachi. Quiero ver la cara de ais cuando aparezca un espíritu mucho más poderoso que su madre y que también puede usar el viento(creo que aster si mal no me equivoque puede usar hielo nieve y por lo tanto también agua y viento en menor medida). Y la de freya cuando empiezan a aparecer personas que se pueden pasar su encanto por las pelotas.
Why are they sticking to the plot of every story? Harry Potter was good since they actually changed the plot but every other world their existence isn't needed since the outcome would be the same with or without them being there. They are sent to worlds to complete their goals, not to babysit the MC. All I've seen so far is your MC following the world MC around and adding some dialogue. Sure he may have defeated some people but those people were bound to be defeated anyways.
the worlds are too weak and the chat group is extremely unbalanced right now, the weak members will struggle but the strong members will steamroll them, idk what you are planning on doing about this lol. All of these world options are dangerous for the weaker ones so they will need babysitting if they go, though the weaker members keep avoiding the missions for "reasons" lol so idk
