In the first few chapters it's setting the MC up against evil witches that were after his grandmother's great grimoire, the last great grimoire in the hands of good witches, but as soon as the MC gets it and becomes a magical girl, his thoughts wasn't to lay low and gather power to defeat the evil witches and get back the other stolen great grimoires, it was that he should stream dungeon clearing in public with his new found powers in order to make money, also everyone gets stronger depending on how many people are watching the stream for some unknown reason (a good regular witch is supposedly behind it because the MCs the only good witch with a great grimoire, why does it feel like "great grimoires" are just tr*sh when compared to the streaming magic?) and people in the world just roll with it. This makes no sense, how have evil organizations not ab*sed this to hell and put world order into chaos, the streaming device literally comes with a virtualization filter to mask the users real identity both digitally and in the real world. Never mind the evil witches who were after the very book that he's publicly flaunting and showing everyone on his streams. The MC does an absolutely horrible job at keeping his identity hidden, he literally walks out of his apartment door in his magical girl form and his neighbor going to work sees him, this happens multiple times! He plays it off as being the little sister, but he's literally publicly told his viewers that he's an older guy, so if at some point that neighbor finds his stream when he becomes more popular, he's doxed immediately. Not to mention that for some reason, he decides to confide in another streamer about his identity and the witches after only meeting them like 3 times because for some reason he absolutely needed the streamer's help to take out the evil fire witch, even though the fire witch was in all senses, a completely dumb 1 dimensional character who apparently had absolutely no special moves aside from shooting out basic hot flames with zero ingenuity despite the fact that they should have unlocked way more techniques because of how long they've had the fire grimoire for. After beating the fire witch the MC basically just continues to out his skills and abilities to anyone and everyone, allies and enemies alike because apparently he wants to goad the enemies to him so he can get their stolen grimoires. The concept of knowing thy enemy, only works for him because the evil witches are all too s*upid to do anything to him even with the amount of information he gives out about his current powers.

All evil witches are also somehow poor as well aside from the fire witch who was a famous public person so they can't come to Japan to wreck the MC for being a complete moron and advertising where he's at to the entire world because of rising plane ticket costs due to dungeons? That also makes no sense. From the way the story has framed it, the evil witches are hundreds of years old and should similarly have a ton of fortune that accrues over their vast life span, one of the books is literally a grimoire focused on the mind, meaning mind control, that witch could easily make money and even take over the world with that power, but no, they're poor and must also be s*upid.

The author puts these evil witches on the back burner and instead focuses on the MCs live streaming and improving his lifestyle, it was like the author didn't know how to make an interesting story about a dungeon live streamer so they added in the TS magical girl aspect to give the MC a reason to become a live streamer. There's essentially zero sense of urgency or threat, everything's going according to the MCs pace even though all evil witches appeared and ganged up against his grandma and caused her death, and here's the MC, a new witch with only a few powers unlocked and the Fire witch gets her ass handed to her almost instantly.
