📖About IFR25KU: The Institute of Fairy Research 2025 Kakera Unofficial
Dreamed of a new fairy!
Monocots ― Order Miragales ― Family Miragaceae A palm-sized fairy in the form of a little girl with butterfly-like wings. Extremely timid, it rarely shows itself to people. When one tries to catch it, it disguises itself as a will-o'-the-wisp and flees; no matter how long you pursue it, you cannot seize it. For this elusive behavior it is known as the “Mirage.” Once regarded as a kind of divine spirit, later research clarified that it is in fact the pollen of Mirage plants, possessing an autonomous structure. |

Overview
IFR25KU is a Minecraft mod that presents a possible world set in the MirageFairy universe.
IFR25KU is an unofficial fork of MF24KU by Yoruno Kakera.
MF24KU was an unofficial fork of MirageFairy2024.
MirageFairy2024 is a mod that expresses the worldview of the MirageFairy project.
This mod adds items, blocks, world generation features, biomes, enchantments, game mechanics, and more.
It lets you experience a possible world set in the MirageFairy universe.
Documents
CHANGELOG is the only official Japanese document that comprehensively describes IFR25KU's specifications.
There are no other official documents; however, some unofficial resources exist, including:
Adventure Guide
What should you do next? Press L to open the Advancements screen.
It will guide you toward your next goals.
Biomes
As you roam the world, you'll encounter biomes reshaped by fairies.
Fairy Forest
Fairy forests dot the land far and wide.
Here, many Mirage Flowers bloom in profusion.
The Phantom Flower found here is difficult to cultivate, yet it serves as a catalyst for higher-tier fairy summoning.
Deep Fairy Forest
A deep, overgrown forest where Haimeviska trees rise like pillars.
Venturing in unprepared is very dangerous.
Fairies
As you journey across the world, you'll encounter many kinds of fairies.
Fairies possess a wide range of abilities.
A light fairy increases your movement speed in bright areas, and an arrow fairy passively boosts your bow damage.
Fairy Dreams
This world is brimming with fairies.
Search among natural and artificial objects alike. When you obtain a low-rarity Fairy Dream, you immediately receive a fairy matching its motif.
The Soul Stream
Press K to open the Soul Stream and place fairies into the top slots of the UI.
They confer powerful enhancements.
Fairy Condensation
Need more fairy power? Having duplicates of the same fairy strengthens its effects.
Cultivate Mirage Flowers to obtain Mirage Flour.
Mirage Flour spawns fairies at random based on the Fairy Dreams you've obtained so far.
Fairies can be condensed without limit.
Magic Plants
Mysterious plants grow throughout the world.
Many can be harvested as crops by right-clicking.
Crossing
Naturally occurring magic plants are born with random trait bits.
Planting them adjacent to one another triggers crossing within the same species.
You have a 25% chance to obtain seeds that inherit both parents’ trait bits.
Crossbreeding
There are many kinds of magic plants.
Using the “Crossbreeding” trait, you can cross two different species within the same family.
Plant Bag
When your inventory overflows with seeds on your journey, the Plant Bag is handy.
World Generation
Weathered Ancient Remnants
As you travel the Overworld, you'll discover Weathered Ancient Remnants.
Try brushing the Suspicious Gravel you find there.
You may unearth a map that leads to the Dripstone Cave Ruin, along with useful materials.
Debris
Debris can be found throughout the world.
These piles can contain early-game vanilla materials as well as materials added by this mod.
You can place items on the ground by pressing Z.
Materials & Processing
Haimeviska
This is a Haimeviska tree. In the fairy language, its name means “great tree of fairies.”
To collect sap for fuel or as a drink, stack Haimeviska Logs to form a wall and score the logs with a sword.
Basic Materials
Felling a Haimeviska is very hard, but a Xarpite Axe—which can break connected logs in one swing—makes the job easy.
As Xarpite’s counterpart, Miranagite is a gem found near the surface. Tools made from it have Silk Touch by default.
Brewing Barrel
Using Haimeviska Logs, you can craft a Brewing Barrel and brew beverages that grant both benefits and drawbacks.
Aura Reflector Furnace
Once you've gathered enough Xarpite, craft an Aura Reflector Furnace.
Miragium produced in the furnace is used to craft powerful tools and also serves as an intermediate material for further recipes.
To run it, you'll need Soul Sand or Soul Soil as fuel.
Fairy House
You can build a Fairy House from Haimeviska Logs and several other materials.
Fairies can live and work there.
Tools
IFR25KU adds a wide variety of tools.
For many vanilla and common materials, all five basic tool types are available.
For mod-added materials, some special tool types may be available.
Special Effects
Many tools have special effects.
For example, the Xarpite Axe provides a tree-felling effect. When you harvest a log, the connected tree is felled in a single swing.
Magical Weapon
The Staff of Miranagi is a magical weapon.
It can be crafted early in the game and fires magical projectiles.
Fairy Jewels
Minia's Telescope
After making some progress in the game, craft Minia's Telescope.
Right-click it once per real-world day to obtain a Fairy Jewel.
Fairy Statue Fountain
Right-click the Fairy Statue Fountain to insert a Fairy Jewel.
It yields a random Fairy Statue, which carries a Fairy Dream.
Lore
Most mod-added items in IFR25KU include flavor text, called a “Poem,” that expresses the IFRKU worldview.
Magic plant traits include detailed descriptions.
Fairy Quest Cards feature several short stories.
Outside the mod, the MFKU official website hosts a series of Japanese articles called “MFA (MirageFairy Article)”.
These resources complement each other and collectively form the IFRKU worldview.
Compatibility
IFR25KU and MF24KU share the same mod ID (miragefairy2024) and are treated by the game as the same mod; their world data is compatible.
IFR25KU v23.23.0 contains game content largely equivalent to MF24KU v22.22.0, so an MF24KU world can be loaded with IFR25KU.
Do not install both together—they conflict.
