Kaikougata Jishin (a Touhou LW original) refers to subduction-zone earthquakes―earthquakes that occur in ocean trenches and troughs on the boundary between an oceanic plate and a continental one. This is the perfect temperament for this Koishi, who enjoys absolute freedom in this world of eternal summer.
The laws of Phases and Essences have been cast aside, leaving a carefree optimism to enjoy the eternal summer and forget about everything else!
''Summer is fun, so an eternal summer is always fun!'' (Strong against Fire Phase.) ''The beach is fun, so you'll always have fun if you go to the beach!'' (Strong against Water Phase.) ''The ocean is FREEDOM!'' (Strong against Star Essence.) ''What? I have to return home by a certain time? No way...'' (Weak against Moon Essence.)
The concept of opening and closing beaches for swimming can only exist in worlds that have distinct seasons. The beach is always open in the world of eternal summer, and this Koishi Komeiji is always having fun, so maybe her eye of love will open one day too.
The Spread Shot of Koishi Komeiji from the world delirious with eternal summer (a Touhou LW original). This attack might have been called ''Growing Pain.'' She uses one of those delivery drones. Wait, why does it look like a gigantic eye...? Is it really a machine? Not a living creature? Unbelievable! Who made such a crazy drone?

The Focus Shot of Koishi Komeiji from the world delirious with eternal summer (a Touhou LW original). This attack might have been called ''Catch and Rose.'' What should have been a rose has become a shell. So many shells wash up on the beach, so collecting them is lots of fun.
Shells kind of look like roses, don't they? Especially the conch shells. Why does the Koishi of this world collect shells and keep them as souvenirs? Does anyone know?

It's always summer here, which means there is always a summer bargain sale. People tend to be freer with their money on vacation, and the heat impairs decision-making, so souvenirs always sell.

A Spell Card of Koishi Komeiji from the world delirious with eternal summer (a Touhou LW original). This attack might have been called ''Rose Hell,'' but this Spell Card seems to have taken on a whole new meaning for the Koishi of this world. You can sometimes feel a connection or fondness for things on sale at souvenir shops, even though you've never seen them before. Like how an animal ornament might look exactly like your beloved pet. Did you know that this is on purpose? The shops secretly research you to make you spend money.

The Lost Word of Koishi Komeiji from the world delirious with eternal summer (a Touhou LW original). This attack might have been called ''Brambly Rose Garden.'' Surely everyone has bought too many things on vacation at least once. But Koishi has the perfect solution. Everything can be safely and securely delivered directly to your home with a single phone call. Somehow, this special service can deliver from anywhere, even from the edge of the universe, forbidden zones, and areas you can only enter by exploiting bugs. But how does it work exactly?
Why do you hear the sounds of ocean waves when you put a shell to your ear? It's because they're played by the fairy living inside the shell who misses the ocean. So... if there's a fairy from space inside, you can make phone calls to space, right?

Character Ability
Capable of manipulating the unconscious mind (Beach)
Expand
The ability of Koishi Komeiji from the world of eternal summer (a Touhou LW original). This ability isn't all that different from the abilities of Koishis from other worlds. Unlike her sister, Satori, and their pets, Koishi was familiar with the surface even before the Underworld got flooded. She is so intent on finding and buying souvenirs because she wants to use them to decorate the entrance of the Palace of the Earth Spirits when they eventually return.
Souvenirs are also called keepsakes or mementos and are intrinsically linked with memories, as shown in one of Satori's Spell Cards. They are a media that stores memory data. Perhaps Koishi collects them as a form of communication. Koishi is a satori youkai with a closed heart and mind, so no one can perceive her memories when they are sealed within her heart. That's why she records her memories somewhere else! Unlike keeping a diary or writing letters, she actually enjoys collecting souvenirs, so she probably won't give it up any time soon. Incidentally, it is said that fossils of shellfish can be found in the mountains.
Some people used to wrongly assume that youkai could keep living in the flooded Underworld because youkai don't need to breathe to live. However, when the Underworld was flooded, it ceased being subterranean and became submerged, and the Palace of the Earth Spirits became the Palace of the Water Spirits. The hot springs also flowed into the ocean, and no one could eat the Hot Spring Town's delicious food anymore. The vengeful spirits would never stay in a place like that, and the oni also got sick of it. There was no other choice but to move to the surface and designate a specific area as part of the Underworld. This, of course, did not mean that the hated youkai were entirely free to live on the surface, as their past with the surface youkai couldn't just be ignored. It's easy to imagine that Koishi helped smoothen the negotiations because she often went to the surface to play before the flood.
''I got lots of souvenirs again today! These are for Satori, these for Okuu, and these are for Orin'' Koishi cannot be remembered, so she wishes to leave memories behind. The souvenirs are the small roadside pebble's feelings of love. Summer evenings at the beach are like illusions, and the sea breeze slightly clears your dizzy head. The girl's feelings that cannot be recorded in history become fossils and leave their mark within the strata of the earth.
Immune to Barrier Status: Paralyze. When attacked with Paralyze, Spirit Power 0.20 UP. For every layer of Barrier Status: Freeze, Yang ATK, Yin ATK, CRIT ATK, and CRIT Accuracy 1 level UP.
DMG to effective elements 50% UP. DMG to resisted elements 10% UP.
''Auctions are also supposed to be popular. People can bid on my rare shells!''

As an attacker
Provides a good amount of Yang ATK and CRIT ATK for the party
Can reach 3P on her 1st turn with her 2nd and 3rd skill
Freeze anomalies increase her damage output substantially
As a supporter
3rd skill is very spammable, allowing for a strong source of buffs
Party wide 1.20 P on her 2nd skill, as well as more power on her Spell Cards and Last Word
Inflicts freeze barriers
As a breaker
A strong emphasis on Star breaks, with supplementing elements on the other Spell Cards
Inflicts Freeze anomalies with her 1st skill and 2nd Spell Card, and breaks them with the same Spell Card and her Last Word.
Story Card Recommendations
(Card recommendations last updated on December 24, 2023)
As with all characters, Spirit Power is a valuable commodity for stages. With Koishi providing power on her spell cards, Myouren Temple Anniversary is a strong option to provide team support with the amount of power she can provide, with The Witch of Scarlet Dreams being a good alternative, if you don’t need the team support. Koishi also would want an extra source of Yang ATK to extend the buffs she may provide, so using cards like Nameless Adventurers can help extend her Yang ATK buffs. Alternatively, she can use Mansion of Memories to help support Yin nukers even further. Finally, if you want to amplify her Last Word’s damage, you can use Yang ATK stat sticks, preferring ones with Agility like Secret Sealing Club Girls or Resort Stars.
Koishi’s Last Word is most effective with cards that boost Heavy bullets. Thus, The Secret God in the Sky and Summer God, Fantasy Sea are the best cards for the job. Alternatively, she can also use Secret Sealing Club Girls as a way to provide some more utility with Evasion DOWN while boosting the Star bullets in her Last Word.
Character Skill Level Up Recommendations
Consider prioritizing her skill 3, Beach Auction, as despite the buffs’ 1 turn duration, it can be extended through external factors like story cards or her own 1st spell card. After which, level up her 2nd skill, Jungle Shopping, mainly to be able to provide party P UP and improve her own accuracy. Finally, her 1st skill, Koishi’s Flea Market, to help in Freeze barrier breaking and further improve her own damage via Freeze self inflict.
Character Strengths
Strong Anomaly Breaks
While she may have a primary focus on Star elements, C3 Koishi’s barrier breaks are at their best when utilizing anomalies to break. With strong access to Freeze anomalies, she can fully break an enemy with ease on the first turn, assuming they are weak to one of her elements.
Powerful and Versatile Support
One powerful utility tool she has is her ability to provide the party with a large amount of Spirit Power. With her Skill 2 providing the party with 1.20 Spirit Power, she augments this further with her Spell Cards and Last Word providing more power, allowing her teammates to be more liberal with their boosts. On top of this, she goes very far to provide Yang ATK, Agility, CRIT ATK and CRIT Accuracy, with Yang ATK and CRIT ATK provided every other turn via Skill 3, albeit coming with only a 1T duration.
Character Weaknesses
Disjointed Skills, Limited Killer Range
While C3 Koishi functions as a Yang nuker and accordingly buffs Yang ATK, her DEF DOWN skill debuffs Yin DEF - this allows her to be able to function with Yin teammates, but will be less useful in Yang-oriented teams where she is stronger. This cumulates in her lack of powerful Killers which limits her growth on setup, with of her more reliable Killers being God, Religious, Beast, Older Sister and Youkai Mountain.
