This is my first review on here so it might not sound too well written or coherent. This show has a very 'Nintendo' feel to it. Like the plot by itself isn't too great but the characters are so charming, and the vibes are so energetic I fully believe it can get a lot of people looking for a simple story on board. Story: Some other MAL reviewer said they like to judge a story based on how well it's balanced with the characters, like weak characters but strong story and vice versa. This show is a very good example of good characters but weak story.There's not really a central overarching plot outside of the rival just trying to take over the city that the anime takes place in. The anime is pretty vague on the actual societal problems that plague 'Night Town', so the most the viewer knows is that it's just a dump. The setting not really being too interesting can tank down a story, and since this whole story is primarily about taking over the setting, it's not too interesting. The show also takes its sweet, SWEET time getting to the actual mystery behind the mechs and not going to lie by the time they actually do reveal it you'll most likely have lost interest by then. Overall, a pretty weak overarching plot with a handful of stellar moments. 5/10.

Characters:
Easily the best part of the shows writing, I truly do love a majority of the characters in this anime from the bottom of my heart. Almost every interaction feels realistic and genuine. So much of the cast just bounce off each other so naturally it's insane, ESPECIALLY in the way the adult characters behave towards the kids. However, I can't mention the characters without mentioning my all-time favorite from this show: Katana. On the surface he can just come across as a very typical rival character, and honestly, he is. But I don't know if it's his design, his English dub voice (which is shared with Kakashi Hatake btw), or just how smooth and overly aggressive every single piece of dialogue that comes from is, but he's great and without a doubt the star of the show in my eyes. Hell, I definitely liked him a lot more than the main character, Hajiki, and this is no slight against him because I loved him a lot too, but he really just doesn't compare to Katana. Every episode that centers around Katana is genuinely a highlight of the whole series, no joke. What's DEFINITELY a lowlight would be two the kid characters: Arashi and Aiko. They both genuinely don't contribute much to the show other than having crushes on the male characters, and normally I wouldn't care as much but when so much of the cast is so good they genuinely stand out with how mediocre their writing is. Despite this, I still love this show's cast to no end and it's definitely the best part of it all to me. That comfy 'community' aspect of this show's cast reminds me of the video Majora's Mask, which might also be a pretty big reason as to why I love them so much.

Music:
I'm not experienced in music and so this section's not going to be long, but this soundtrack is godly. This is coming from someone who doesn't even care for jazz that much, the main genre of this show's OST, but every, and I mean EVERY track is either so catchy or so memorable I can't hate it. There are definitely some standout tracks of the show and trust me when you hear them you'll now them.

Visuals:
The lighting is genuinely some of the best in not just any 2000s anime but in a lot of anime in general. I'm not going to lie, I'm a heavy fan of more muted, subdued colors in anime, especially in 2000s anime. It's one of the main reasons why FMA 03 is one of my favorite anime of all time. The lighting is easily the third best part of the show, and I genuinely don't think any sane human being with an eye for lighting wouldn't recognize it. I also adore the character designs, every single one of them, from how 1930s 'Tom and Jerry'-esque gangster Katana looks, to the cool more 2000s urban look of Hajiki. That being said though, when the show is saving on budget, you can tell. Especially since it's a 2000s anime and ESPECIALLY since all of the kid characters have very simplified designs, and my belief when it comes to anime is that if the character designs are going to be simple it should usually have stellar animation to back it up (Mob Psycho 100 or for a more 2000s example, FMA 03), but this anime doesn't really have what I would call 'stellar animation'. Despite that though, the fight scenes are genuinely still entertaining, primarily due to the high-speed movement of the mechas.

Overall:
If you're coming into this show expecting writing on par with some of the greats of mecha anime, or even just 2000s anime, it's not here. However, if you just want a simple fun show with a very charming cast, pretty great visuals, and an amazingly catchy soundtrack, then hopefully this review convinces at least someone out there on the internet to watch this. Overall, a solid 8/10 for me.
