God, the MC is such a boring character.
It wouldn't have been hard to make him entertaining. Like, him reflexively splatting the old lady's familiar "because it's gross" or some other "I've been through Hell and my filter was the casualty" moment. Sagara Sousuke from Full Metal Panic! is like a perfect example of what this character should've been.
This chapter amounts to him just meekly sitting around while a room full of lunatics acts like lunatics in front of him.
