Fantasy setting that begins in a school. Male MC looks exactly like the previous/former hero and thus judged much more harshly by his peers, especially because he’s got average-ish talent. His senior/senpai (FL #1) turns out to be an Angel- or rather, THE Angel who was part of the former hero’s party, and takes him away from the school. They pair up with other women from the former hero’s party, eventually learning that MC has a talent in spirit summoning (or something along those lines, such as elemental). Last I remember was that they were at a volcano adjacent town, and either the volcano was going to erupt or the town was under attack by beings who made the volcano their base, and the group went towards the volcano. Also something about the MC constantly doing sword training using falling leaves or rain? I also remember a dragon being one of the FLs, and maybe a demon?
