Am I the only one who thinks this?

I really don't want this guy to join the main group and I don't care if he has a tragic past like abusive parents or something. For starters, "the research group" is already large enough to accommodate one more member. Additionally, the character is personally very unpleasant since his interactions with Okarun and his comments to Ayase. He currently wants to beat Okarun because his ego is hurt from being defeated by Okarun in the track and field events and why Okarun became more popular among girls. Does anyone really prefer that this boy join the group and leave Miko and Muko more forgotten? Anyway, this is my personal opinion and I'm not looking to offend anyone.
