(I'm writing that review after vol3)
It's a quite good series which manages to balance elements that are usually kinda bad in other LN, with good characters, good interaction, and later some good comedy.
The story mainly follows a priest who is assigned the mission of helping the summon hero to beat the demon lord but the hero turns out to be quite strange and expel I'm from the party, therefore he is forced to help him from the shadow.
The story succeeds on a number of points which are usually bad in a lot of LN:
- First the jerk hero, who at first appears like
your run of the mill bad hero who is a moron for no reason. But here the series give logical reasons for the hero actions and show that while he can take strange actions at times he is aware of the consequences they could bring and not just doing things on a whim.
- Second the powerful support MC: the series does a good job at showing that he is powerful while showing that he also has weaknesses which could easily doom him. The author also doesn’t forget who the hero is, and while it mainly follows the priest, it didn't try to make him take the hero place. The MC is a support character and will eventually be outperformed by the hero.
- Third the video game world, unlike a number of LN where it's just is a video game world for no real reason, here that aspect quickly gets a logical explanation.
The best part of the story is probably the characters, most of them are quite original and more importantly, the important one (hero's party, priest's party) are all 2-dimensional characters. The MC is especially good as a workaholic sarcastic jerk and his interactions with his assistant (kind of the same personality) are really interesting. The series also does a good job at developing characters, even if it's mainly the hero party who changes since they are the one growing while the MC and his party are already accomplished.
A part where the series is lacking tho is the story. It's not bad but not fantastic and while it will probably become better when the conflict with the demon really starts, so far it has mostly been following the plan decide in vol1 without much change.
The art is good most of the time, not much fanservice so far, but well it's a novel who cares about the pictures.
Ps: I usually wouldn't do that, but: don't give too much importance to the first review, its main issue with the series is in fact not an issue and is resolve and explain by the end of vol1.
