I really liked this show. The girls are great, every one Except boring as fuck Machi.
But even better than the girls is Sensei. He's not just a buff Chad, but the pinnacle of what I was taught to aspire to as a man. He's strong, but caring and able to follow through and do what he can for all the girls. He approaches things methodically, from multiple angles, and solves other's problems proactively.
Sensei is the best anime protagonist. Full stop.
