At this point we have some things established:

• MC is very much a Ciaphas Cain/Lightspeed Masayuki style character, does not want absolutely anything with the hero thing but is pushed to it by external circumstances AND must act like it because the consequences of the whole thing ending would be BAD, i utterly love this
• Narrative Causality itself is having an absolute blast making everything the MC does look like he’s a super-competent hero, when in reality he’s just messing around and trying to NOT be a hero
• There’s too much fanservice around Tino, and doesn’t look like it’s gonna stop
• The abusive relationship between Tino and her sensei Liz seems to be played for laughs but is rather offputing

Both very good and very bad things about this series, i think the good are worth remaining but that might change
