Using LP on nonsense things is really stupid. It’s like pulling for something you don’t even need using your last gem in a gacha game. Not even thinking about what could happen if he needs it in an emergency, lol. I already felt earlier that this anime doesn’t really run on logic. The content of this episode is mostly fan service and comedy. It looks like a filler episode. It’s not that important to the story progression, and you can definitely skip it. The only part that progresses here is the introduction of a new transferee.
