5 stars for having Eris from Asobi ni Iku Yo!... Now onto the novel itself... well, there are some things i dislike but since im not a stupid left person i won't scream to cancel you LOL. The grammar is above average, the story is well... THERE but it needs improvement. Character Design is surprisingly good... As for world background... this needs to be developed a lot more.
Now onto the system... Well, it's easy mode for MC basically. There are some novels where there is a system, but mc has to struggle and work hard to achieve things and the system aids him... But here, mc can choose whatever he wants lol. Nothing is explained about how mc arrived to that world, how long ago that was. It starts with mc already being extremely powerful after being transmigrated. Recently some dimensional alien appeared as the first "Villian/Monster" but i doubt it will be hard to beat.
The novel is more focused on a slice of life within a fantasy setting with a comedy taste to it with an overpowered mc. Also, author provides us with different POV of the heroines which is interesting... And speaking of this... the School "LOCKDOWN" Festival... well, boring lol, while the topic is interesting, its boring since we know mc will win it all. There is no suspense at all. MC so far is completely flawless, and that makes him a bad character, he is like the "Almost Perfect" Man, and i say almost because there will be always something you dont like about him. ME? I don't like Dreadlocks, i believe they are filthy and mc keeps them clean using magic lol, but this is just my personal opinion. Aside from that its very good... Just a friendly reminder to author... There hasn't existed and there will never exist a character that 100% of the readers will like. There will be always something that your character has that someone else will not like. SO the ideal will be to make character that YOU like and that hopefully, most of the readers will also like. (or hate, depending on what you want lol... if you made a character so that it can be hated, and everyone hated it, you did a good job lol)
