This episode feels like a breeze to me. Ishiki's sacrifice was useless though it strengthen the brotherhood in exchange of love life but still in the end he got lucky with Kumin-senpai
Though the good part for me is the in front of the train, holding hands with Rikka. That felt great but this entire episode feels like a filler with foreshadowing of something to come from what the priestess said and she also ask help from Yuuta. Maybe the parents are coming to visit and.... well it looks like Rikka and her parents aren't in good terms.
