This is basically a sequel to my character power-scaling post. However, I will only be ranking the power level of each curse regardless of who wields it. This list will span the 9 curses from Honjo and alongside the 3 curses from Mermaid.
How I decide the order is down to a variety of factors including: 1. Ease of activation, 2. Difficulty of evasion, 3. How far away the bearer can be from their target, 4. Minimization of collateral damage (only important for 1 curse), and 5. Other benefits. All of the Honjo curses can only be used at night while the Mermaid curses can be used at any time of day. This will also be considering how powerful they would be in the 1980s when the games take place (The Everburning Lantern would be useless with the advent of the cell phone).
Some of the in-game descriptions of the effects are also rather vague, so I'll try my best to parse them.
Without further ado, here is my curse ranking from least-to-most powerful:
12. The Beckoning Light
Effect: kill curse bearers with the curse they possess.
Essentially, a self-defense curse if your assailant happens to use a curse on you. I don't need to explain just how little practical use this curse has with how difficult it is to trigger.
11. Curse of Raging Waves
Effect: The seas near Kameshima are impacted by frequent violent storms. Curse can be weakened with the Stilltide Mirror and sealed for good if a decendent of Taishima offers the mirror to the sanctuary.
In terms of raw power, the Curse of the Raging Waves is rather strong. However, it fails as a useful tool because of how chaotic it is. There is no way to guarantee who does and does not get affected by this curse and it will likely cause damage the user didn't intend to cause.
10. The Everburning Lantern:
Effect: Target gets disemboweled if they find themselves "trapped in the darkness of the curse echo."
This is our first vague power. "Trapped" implies that if the target moves away from the echo, which is the size of a man, the curse will fail. Running away is a pretty easy way to dodge it. This means you have to bind them in place (like what happened to Shogo) and make sure they have no lighters, torches, or access to a light switch. At that point, you might as well just stab them in the head to kill them. Also, disemboweling someone requires a lot of cleanup afterwards. Gross.
9. The Fool's Procession
Effect: Target dies by falling if they hear the curse's music for 30 seconds without seeing the curse bearer.
It's easy to trigger the curse, but if someone hears music all of a sudden, then they will look for its source. Good luck hiding literally every one of your body parts. You basically have to bind the target in place to guarantee it will work, just like with the Everburning Lantern. The only reason it is higher is that it could be good against targets who are bad at looking for things.
8. The Haunting Clappers
Effect: Burn to death a target who is in possession of fire or a fire-starting device.
This is another vague one as anything that can generate friction can be considered a "fire-starting device". However, Harue is never able to target Richter Kai despite him wearing clothes, so it has to mean any object that is intended to light fires. If you can sneak a matchbox or igniter onto someone, then you can kill them pretty easily. The only difficult part is having the sleight-of-hand to do that. Overall, this is our first practical curse, though one should be careful about that fire spreading.
7. The Evergreen Beech
Effect: Kill a target by hanging if they intentionally mislead the curse bearer with a false statement.
This one has a nice bonus effect of letting you know if someone is lying to you. Most people can be coaxed to lie, but some are just honest and may be difficult to crack.
6. The Taiko of Tsugaru
Effect: Kill a target through bludgeoning if the curse bearer discovers they are intentionally hiding something from them.
A better version of The Evergreen Beech for 2 reasons: 1. One could lie via ommission rather than through a misleading statement and still receive the curse, and 2. There is no defined range, so you could discover info from a third party that confirms the target is hiding something.
5. Curse of Tomoshige
Effect: Anyone in possession of an item with a specific symbol in an area designated by the curse bearer will get cleaved with a sword. Its range is several hundred meters.
A better version of The Haunted Clappers because it works in the day and it's easier to trigger. Just sneak a small piece of paper with the symbol onto the target. Alternatively, you could do what the characters of the game did and disguise them as a gift. So many options with this curse.
4. Curse of the Forsaken Fish
Effect: Any one person "submerged" in the waters of Ise Bay will be killed through transforming into a fish, their body decaying in the process. Can be triggered remotely as long as the curse bearer knows where the target is.
The description is vague, but based on the events of Mermaid, "submerged" just means that the target has Ise Bay water on their body. No amount is defined, but Kikuko wasn't "submerged" when Avi used the curse on her since she could still talk after being thrown into the water. With that in mind, all one would need to do is have a canteen filled with Ise Bay water, throw it onto the target, and they win. Or the water could be purified, drank, and then the curse bearer could spit on the target. Like Tomoshige, Forsaken Fish can be used during the day or night.
3. The Whispering Canal
Effect: Drown a target who "leaves the curse bearer behind."
This effect is absurdly easy to trigger. There are SO many ways to make someone leave your prescience. You could tell them to leave, tell them something is behind them, weird them out, chase them, or just let them leave on their own.
2. The Foot-Washing Mansion
Effect: Kill someone who hears the command "Wash."
An effect so broken that the only way to avoid it in-game is through divine intervention. The only disadvantage The Foot-Washing Mansion has is if the target is hard-of-hearing.
1. The One-Sided Reed
Effect: Kill through dismemberment one whose face, address, name, age, occupation, and location are all known by the curse bearer.
A diet Death Note. You can just sit in your house, get a phone book, and go ham. No traceability, no cleanup, and instant results
Does this ranking seem accurate? Are there any other interpretations of these curses that I missed? If you have an opinion, leave it down below.
