These are basically weaker than Teigus and well, they are "Bootleg" as in there are NEGATIVE effects. 400 years ago, The Emperor wanted to make his own Teigu but failed to surpass them so he locked them away because they suck and as nowhere near as strong as Teigus. Even though Shingus are strong, they can have consequences later. Now after a long while, they have been released and have been given to Akame and her teammates. There are 7 confirmed so far.

1. "Pulverization King": An arm-brace shingu that grants the user super-human strength.

Negative Effect: Incorrect usage of it will damage its user.

My thoughts: Well. You get super strength, that's a plus but if I use it wrong, my arm would break and twist, or get ripped apart or something. I don't know what incorrect usage would even mean for this shingu. Like what? If you punch like 5 steel walls, would this shingu like destroy your arm or something? Or maybe even a wrong twist or movement in the arm will make the Shingu backfire.

2. "Sidewinder": A Shingu that can move as commanded by it's user.

Negative Effect: Hard to control due to it's unique style.

My thoughts: Okay so we got an unruly and out of control tengu. At least "Belvaac" controls better than the shingu but we all know teigus are superior. What we might see later on Akame is that maybe Sidewinder might kill it's user by whipping, choking the neck or bind the user.

User: Green

3. "Yocto-Bottoms": A fabric Shingu that increases acceleration and leg strength.

Negative Effect: Doesn't really increase much so the user's strength is still important.

My thoughts: So it boosts my legs but not that much huh? I mean, it's good for people who run/walk a lot or use their legs a lot but if you snipe or cut their legs off, the shingu is useless.

4. "Water Dragon Sword": A sword Shingu that makes the user stronger for 3 minutes.

Negative Effect: After 3 minutes, the user will be severely fatigued afterwards.

My thoughts: Prolonged battles are not a good idea when you use this Shingu. Heck, maybe you can wear the user down with stalling, traps or mind-games. The shingu is not specific either, stronger in what? Strength? Senses? More focus?

5. "Rhea Suit": An Armor-type Shingu that is designed to use Earth to its advantage and can dig underground.

Negative Effect: It cannot create earth from nothing and it heavily strains the user.

My thoughts: So a shitty version of "Black Chariot"/"Incursio" huh? If you also fight in the ocean, Good Game Gai. The only thing this shingu is good at if you fight on a cave or have huge rocks surrounding you. Digging Underground is useful though but well, it puts a strain.

6. "Prometheus": A gun Shingu that can shoot arched, reflected and other types of bullets

Negative Effect: Repeated Usage will decrease its accuracy.

My thoughts: This is way better than most of the shingu already discussed. It may not be as powerful as "Pumpkin" or "Rubicante" but it's good for assassinating but only like 1, 2 or 3 targets. If you face an army, yeah, the user is fucked bad unless the user already knows how to aim better therefore making the negative effect somewhat moot.

7. "Kiriichimonji": A Blade Shingu that inflicts wounds that cannot be healed.

Negative Effect: None so far.

My thoughts: Murasame's Little Sister. The only negative effects about this you accidentally cut yourself or a friend or a family member with it.
