I made this as part of my Patreon. Feel free to join it to vote on characters and blogs I’ll do in the future. The next prediction blog will be Meta Knight vs Zero.
Also I wanna encourage everyone to read another blog on this match made by a friend of mine named Kirbonic. I would argue his version is more thorough than my own! He did a great job so leave him a comment.
Background
Kasen
The main protagonist of the Horned Hermit side story. Kasen is one of many youkai(essentially spirits) living in the area of Gensokyo. Gensokyo being a special location residing behind a dimensional barrier where spirits that depend on the spiritual belief of mankind live. Kasen spends most of her series getting to know Touhou main character Reimu, a girl tasked with protecting Gensokyo and Hakurei shrine from malevolent youkai that could disrupt balance of the location. She’s also introduced as a “hermit”, a person who’s gained enhanced spiritual strength through religious training.
The main premise of the Touhou series is to protect the Hakurei shrine and Gensokyo https://en.touhouwiki.net/wiki/Story_of_Eastern_Wonderland/Story/Prologue
Kasen is introduced. She’s a Hermit https://mangadex.org/chapter/4f945a70-a8cc-44b6-92fc-985a5b3458e6/17
Kasen came to the Hakurei Shrine https://mangadex.org/chapter/4f945a70-a8cc-44b6-92fc-985a5b3458e6/25
Eventually it is revealed that Kasen was once an evil Oni spirit, and was a member of the “four devas”. In her past she was defeated in battle and the evil within her was essentially sliced off of her in the form of a severed arm. Kasen then chose to essentially reformed herself.
Kasen is revealed to be an Oni https://mangadex.org/chapter/cac3371e-1fb1-4cb1-a9bf-e1f49de43a8c/26
Kasen lost her arm when it was sliced off in a battle. This arm contained her malice and was sealed away. She then reformed herself and became a hermit https://mangadex.org/chapter/7d872f88-8279-4787-b9d2-1f06322093ce/3 https://mangadex.org/chapter/7d872f88-8279-4787-b9d2-1f06322093ce/13
Over the course of her story the seal on this arm weakened, causing it to manifest as an evil version of Kasen and eventually fuse with her. However by manipulating events in her favor Kasen is able to get series protagonist Reimu to excise the evil in the form of her severed arm once again.
Kasen tried to reseal her arm when its seal weakened https://mangadex.org/chapter/7d872f88-8279-4787-b9d2-1f06322093ce/6

Reimu defeats and saves Kasen https://mangadex.org/chapter/7d872f88-8279-4787-b9d2-1f06322093ce/45

Kasen owns a mansion and becomes friends with Reimu https://mangadex.org/chapter/2c0cfd03-0832-409e-a589-23b4fbd3fbab/12
Sonic
Sonic’s background in Fleetway is somewhat different compared to most Sonic continuities. In this universe he was originally a normal brown haired hedgehog, and only gained his blue spikes after breaking the sound barrier. Sonic green eyes were also the result of exposure to energy from the monster chaos.

Coming into contact with Chaos made Sonic’s eyes green https://readcomiconline.li/Comic/Sonic-the-Comic/Issue-179?id=61981#2
Sonic and Robotnik were also originally friends in this continuity. Robotnik initially went by the name “Kintobar” and worked with Sonic to try remove evil from the planet with an experiment using the chaos emeralds. It was a freak accident with Kintobar’s evil computer system and the contamination from a rotten egg that caused Kintobar to become the evil Robotnik. Ironically it’s later shown Sonic himself sabotaged the machine via time travel hijinks.
Robotnik was created via an explosion of the chaos emeralds and a rotten egg https://readcomiconline.li/Comic/Sonic-the-Comic/Issue-8?id=62103#8

Abilities
Kasen
Magic
Magical spiritual energy that can be used to fuel various forms of attack or phenomenon. Some of the more notable applications of magic is to directly attack the soul or spirit of others, as well as altering fortune (probability) in your favor. Control over fortune can also prevent interference of other aspects of magic from working.
It’s stated magic spell cards can deal spiritual damage https://hisouten.koumakan.jp/wiki/Aya_Shameimaru/Spell_Cards

Spell cards/Danmaku
Spell cards are “designated” names for magical attacks, moves and abilities used in the Touhou universe. In gameplay of the series these are typically utilized to form the energy “bullet patterns” of energy spheres and attacks, aka Danmaku. In older titles these skills were activated using actual “cards”, but that concept has since been dropped.
Spell cards exist in the universe as part of a “duel” system that series protag Rimiru created to settle disputes. Both sides of a conflict typically agree to what spell cards can be utilized during a given fight, and victory is typically awarded based on who has the most visually stunning performance or visual aesthetic of their attack rather than their raw power. As spell cards attacks are intended for formal duels, they “generally” aren't intended to be lethal. Though obviously common sense dictates a user could choose to use similar attacks in a lethal way if they want.
Spell cards are forms of magic that are given a name and specalized appearance https://en.touhouwiki.net/wiki/Imperishable_Night/Afterword

Sonic
Super Sonic
A corrupted “superform” caused by Sonic’s exposure to the evil tainted chaos energy at the start of his series. Unlike most series Fleetway Super Sonic is an aggressive alter ego, who is much more aggressive and destructive than the normal Sonic.
Sonic absorbed chaos emerald energy and this is what created Super Sonic https://readcomiconline.li/Comic/Sonic-the-Comic/Issue-27?id=62048#19 https://readcomiconline.li/Comic/Sonic-the-Comic/Issue-27?id=62048#20 https://readcomiconline.li/Comic/Sonic-the-Comic/Issue-27?id=62048#21
Sonic says after absorbing some chaos energy he became able to go Super when stressed https://readcomiconline.li/Comic/Sonic-the-Comic/Issue-84?id=62108#4
Super Sonic can use chaos control http://www.stconline.co.uk/comics/stc266/
Additionally Sonic does NOT need chaos emeralds on hand to become Super Sonic. While the form can be forcibly activated in the presence of chaos or ring energy, Sonic can transform at any time when undergoing enough physical or mental stress. In these cases the form will just run off any latent ring/chaos energy Sonic has in his body.
Super Sonic appears in times of great stress or exposure to chaos energy http://www.stconline.co.uk/comics/stc262/
Transforming via chaos/Ring energy
Sonic spontaneously enters the Super sonic form. It’s stated this has happened before when he absorbed to many rings https://readcomiconline.li/Comic/Sonic-the-Comic/Issue-7?id=62092#7

Time limit
Super Sonic does still have a time limit of sorts, though it's less defined than other continuities. Without a constant source of chaos energy Sonic will revert back to his normal form “eventually”. Likewise while Super Sonic was once able to exist as his own separate entity for a time, he was in danger of dying after going for a long period of time without chaos energy. Thus implying he can’t operate at full strength indefinitely.

Hyper Sonic
A new Superform exclusive to Sonic the comic online. After having the evil in Super Sonic and the chaos emeralds purified, Sonic was able to utilize emerald energy in a more positive manner to form Hyper Sonic. This form has all of Super Sonic’s powers, but with the benefit of keeping Sonic himself in control.
It's stated that Sonic was evil in his super form because the original chaos energy he was exposed to was contaminated with evil. After being purified and absorbing normal chaos energy sonic becomes hyper sonic http://www.stconline.co.uk/comics/stc275/

Verdict
I’m probably going to keep things fairly short. In terms of stats it's pretty obvious that base Sonic is weaker than most high end Touhou characters. As far as I’m aware Sonic can’t blow up universes or whatever. I’d also say that “abilities” wise base Sonic doesn’t really have a lot out of the ordinary compared to most other versions of sonic. It’s mainly the spin dash, standard applications of super speed and maybe some tertiary stuff from early games if you want to lean into the idea of them being technically cannon to Fleetway.
The argument is “mainly” between Kasen and Super Sonic or Hyper Sonic.
Anyway in terms of raw power I’ll probably argue both are equal enough in speed. Both can scale to feats of crossing infinite distances or affecting entire spacetimes. In terms of strength I would probably agree with arguments that Touhou seems to have more leeway in terms of cosmology.
In the main comics proper Fleetway Sonic “mostly” just established the main universe and special zone in terms of universe size dimensions. There were a couple of arguments for expanding outside of that, such as the mirror universe, atomic universe, limbo and a few other pocket dimensions, but they typically were less clear cut or elaborated on. You really need to lean into the more obscure novels to find arguments for numerous timelines or full alternate dimensions existing. Touhou (IMO) seems to have much more dimensions in its main cannon, and heaven alone could be calculated to be huge based on the size of Amibtabha and technically is sorta its own multiverse. So I would lean on Kasen taking power giving both side equal levity(there's also DT arguments for both sides, but fuck that lmao).
Abilities wise I think Kasen probably outdoes Super Sonic in terms of abilities she’s actually displayed. Many of the chaos powers that could give Super or Hyper Sonic an advantage are technically powers he never personally showcased. He’s almost been portrayed like a strength based brawler, not a reality warping entity similar to God Robotnik. That said, even granting Super Sonic all chaos powers seen in the series, I think Kasen can probably counter everything that matters.
Transmutation and size alteration: Youkai can alter their form and are not dependent on physical bodies anyway.
Teleportation: Kasen can do this too more or less
Timeline alteration: There’s Touhou characters who can do this, and control over Fortune/probability should help mitigate this.
Memory alteration: Has resistance via true moon resistance
Regeneration: Kasen seemingly also has resistance to this.
I’ll give Sonic one advantage, the time limit in Fleetway is way more “arguable” than most other Sonic series. I don’t think you could just outlast his super form as easily, and you could argue that Super Sonic could run indefinitely depending on the circumstances. But even if Super Sonic was as strong as Kasen I don’t think he’d be insurmountable. Super Sonic has been removed from Sonic before, Super Sonic has been imprisoned/sealed before. Both of which feels like Kasen could do given her ability to remove souls or her sending Remi to Avci.
Kasen ultimately seems to have the most advantages, so I’m gonna side in her favor.
