Are you ready to master one of the most dynamic and powerful breathing styles in Weak Legacy 2? The Insect Breathing rework has completely transformed this style into a versatile powerhouse with three distinct modes: Bee Mode, Butterfly Mode, and the legendary Horsefly Mode. As someone who has spent countless hours testing and perfecting the methods to unlock each form, I’m excited to share this comprehensive guide that will take you from novice to Insect Breathing master.

In this complete walkthrough, you’ll discover exactly how to unlock each mode, where to find Shinobu Kocho, the most efficient farming strategies, and pro tips that most players miss. Whether you’re looking to dominate in PvP or become a farming machine in PvE, this guide has everything you need to master the reworked Insect Breathing style.

Quick Overview: Insect Breathing Modes

Mode	Unlock Method	Difficulty	Best For
Bee Mode	Complete Shinobu’s quest	Medium	Speed combos & beginners
Butterfly Mode	Automatic after Bee Mode	Easy	Balanced combat & agility
Horsefly Mode	RNG drop from Shinobu	Hard	Maximum damage & endgame

Understanding the Insect Breathing Rework

The Insect Breathing style received a massive rework in Update 4.75, transforming it from a single-form style into a progressive system with three unique transformations. This rework has made Insect Breathing one of the top-tier choices for both PvP and PvE, ranking among the best V1 breathing styles in the game.

According to current tier lists, Insect Breathing maintains an S-tier ranking for both PvE and PvP, thanks to its excellent combo potential, extreme mobility, and high damage output. The rework didn’t add a V2 version, but the three-mode system provides enough versatility to compete with V2 styles.

Step-by-Step Guide to Unlocking Insect Breathing

Step 1: Locate Shinobu and Start the Quest

Your journey to mastering Insect Breathing begins with finding Shinobu Kocho, the Insect Hashira. Based on my research and multiple sources, here’s exactly where to find her:

Location: Shinobu is situated in a house close to Mitsuri at the Demon Slayer Corps Village. This is a crucial detail, as many players waste hours searching in the wrong areas.

Requirements to Start:

Be at least Level 15
Have basic combat experience
Be prepared for a challenging questline

When you first approach Shinobu, she’ll offer you the Insect Breathing quest. Accept it to begin your journey toward unlocking the first mode.

Step 2: Unlock Bee Mode

Bee Mode is your first major goal and the gateway to the entire Insect Breathing progression system. To unlock it, you’ll need to complete several challenging objectives:

Gather Required Materials

First, you’ll need to collect two essential resources:

150 Demon Horns – These are dropped by demon-type enemies throughout the game
500,000 Yen – The in-game currency required for the training

Pro Tip for Demon Horn Farming: Focus on areas with high demon spawn rates. The Slayer Corps area and surrounding regions typically have the best density of demon enemies. I recommend farming during 2x drop rate weekends (automatically applied every Saturday-Sunday) to maximize your efficiency.

Find the Three Hidden Bees

Shinobu will task you with finding three bees hidden within the Slayer Corps area. This is where many players get stuck, so pay close attention:

Randomized Locations: The three bees spawn in random locations throughout the Slayer Corps area
Thorough Search Required: Check every corner, including rooftops, behind buildings, and in less obvious spots
Patience is Key: Don’t rush this step. Take your time to explore every nook and cranny

Personal Experience: When I was searching for the bees, I found that they often spawn in elevated areas or behind structures that players typically overlook. Make sure to check the rooftops of buildings in the Slayer Corps area.

Defeat Shinobu Twice

This is arguably the most challenging part of unlocking Bee Mode. You must defeat Shinobu in combat two times. Here’s what you need to know:

Shinobu’s Combat Patterns:

Fast, agile movements that can be hard to track
Poison-based attacks that can quickly whittle down your health
Combo chains that can stun-lock you if you’re not careful

Preparation Tips:

Ensure you have a strong breathing style already equipped
Stock up on healing items before attempting the fights
Learn her attack patterns by observing her movements
Consider bringing a friend for backup if you’re struggling

Once you’ve completed all three requirements (materials, bees, and victories), Bee Mode will be permanently unlocked for your character.

Step 3: Acquire Butterfly Mode

Here’s some great news: Butterfly Mode is unlocked automatically immediately after you obtain Bee Mode. There’s no additional quest or material cost required.

Butterfly Mode Features:

Enhanced dash speed for better mobility
Smoother, more fluid attack animations
Improved poison-based techniques
Perfect balance between Bee and Horsefly Modes

Butterfly Mode serves as an excellent intermediate form, giving you a taste of the enhanced capabilities while you work toward the ultimate Horsefly Mode.

Step 4: Unlock the Rare Horsefly Mode

Horsefly Mode is the pinnacle of Insect Breathing and the most challenging to obtain. This mode requires both luck and persistence.

The Farming Method

After unlocking Bee Mode, you can continue to challenge and defeat the Shinobu NPC. Each victory gives you a chance to obtain Horsefly Mode.

Understanding the RNG Drop System

Important: Horsefly Mode has a low random chance to drop as a reward upon defeating Shinobu. There is no guaranteed number of wins – it’s entirely based on RNG (Random Number Generation).

Farming Strategy:

Use a Private Server to farm without interference from other players
Bring healing items or a strong ally to make fights quicker
Set a routine for farming sessions to maintain efficiency
Keep track of your attempts to stay motivated

Personal Tip: I’ve found that farming in private servers is significantly more efficient. Not only do you avoid PvP interruptions, but you can also develop a consistent rhythm for defeating Shinobu quickly.

2026 Advanced Tips and Strategies

Efficient Demon Horn Farming Routes

Based on my experience, here are the best farming routes for Demon Horns:

Slayer Corps Perimeter: Circle around the Slayer Corps area, focusing on demon spawn points
Forest Areas: The wooded regions near main villages often have high demon concentrations
Night Time Farming: Demons spawn more frequently during in-game night cycles

Shinobu Fight Optimization

To consistently defeat Shinobu, master these techniques:

Movement Patterns:

Keep moving to avoid her poison attacks
Use dash abilities to close distance quickly
Learn to predict her leap attacks

Combo Strategies:

Start with quick attacks to build up damage
Use your strongest abilities when she’s stunned
Maintain pressure to prevent her from using special moves

Horsefly Mode Farming Psychology

The grind for Horsefly Mode can be mentally taxing. Here’s how to stay motivated:

Set realistic goals (e.g., 10 attempts per session)
Take breaks to avoid burnout
Celebrate small victories (consistent Shinobu defeats)
Remember that each attempt brings you closer to the drop

Insect Breathing in PvP vs PvE (2026)

PvP Performance

Insect Breathing excels in PvP combat, particularly with Bee and Horsefly Modes. Here’s why:

Advantages:

Excellent combo potential for locking down opponents
Horsefly Mode offers burst damage that can turn fights around

PvP Strategy:

Use Bee Mode for hit-and-run tactics
Switch to Butterfly Mode for sustained fights
Pull out Horsefly Mode when you need to finish opponents quickly

PvE Effectiveness

For farming and boss fights, Insect Breathing is equally impressive:

Strengths:

Area-of-effect capabilities in all modes
Sustained damage for longer fights
Mobility for avoiding boss attacks
Poison effects work well on tougher enemies

Farming Recommendations:

Bee Mode is excellent for clearing groups of weaker enemies

Common Mistakes to Avoid

Based on my experience helping players master Insect Breathing, here are the most common mistakes and how to avoid them:

1. Skipping Proper Preparation

Many players rush into the Shinobu fight without adequate preparation. Always ensure you have:

Sufficient healing items
A good understanding of your current breathing style
Appropriate gear and stats for your level

2. Ignoring the Bee Search

The three bees can be frustrating to find, but don’t give up! Players who skip thorough searching often miss crucial progression steps.

3. Underestimating Horsefly Mode Grind

The RNG nature of Horsefly Mode can be discouraging. Set realistic expectations and don’t get discouraged by the grind.

4. Neglecting Mode Switching

Each mode has specific strengths. Learn when to switch between modes for maximum effectiveness.
