So I decided to rewatch some of my favorite episodes from MHA and I got to the final episode of Season 3 where Mirio destroys Class-1A and he explains his quirk. He says that when he is unable to see, hear, breath or feel while phasing. He also says that when he phases he starts falling and then he solidifies to come flying up through the ground. Which totally makes sense! But in the previous episode he somehow sticks only his face through the wall and ground as he talks to Deku. Meaning he somehow phased only his face through the wall and was able to see, hear and breath while doing so with no problem at all. He was also able to hold himself in place in the ground rather than being shot upward like he describes at the end of episode 25. Did I miss something incredibly obvious or is this just typical "Stop overthinking it" plot shenanigans?
