The KonoSuba collaboration event in Sword x Staff is giving away a free exclusive Fantomon that fans do not want to miss. If you want to know how to get free Chomusuke in Sword x Staff without spending any in-game currency, this guide will walk you through the exact steps. I have broken the entire process down into five simple actions that take less than five minutes per day.
Chomusuke is not a regular reward you can farm from monsters or buy from a shop. It is a limited-time collaboration pet tied to the God’s Blessing On This Wonderful World 3 crossover event. Our team checked the Discord sign-in process this week, and it is still active for 2026.
Before you start, I recommend reading our Sword x Staff progression guide to make sure your account is ready for the new companion. The event is open to all players, so even new accounts can participate.

What Is Chomusuke and Why It Matters
Chomusuke is a Fantomon, which is the companion and pet system inside Sword x Staff. It comes from the anime KonoSuba, where it appears as a mysterious black cat with magical abilities. In the game, it functions as a combat companion that follows your character and provides passive bonuses during fights.
What makes this reward special is that you cannot obtain it through normal gameplay. There is no gacha banner, no shop listing, and no monster drop for this particular Fantomon. The only way to add it to your collection right now is through the 3-day Discord sign-in event running during the collaboration period.
Players in the Reddit community have been reminding each other daily about this event because it is genuinely free. Active community members note that this is one of the rare instances where a crossover pet costs zero resources. If you care about collecting exclusive items or improving your companion roster, missing this window would be a mistake.
How to Get Free Chomusuke in Sword x Staff
The process requires joining the official Discord server and posting in a specific channel for three consecutive days. Here is the exact sequence that worked for me and dozens of other players this week.
What You Need Before You Start
Make sure you have the game installed and can access your account. You also need a Discord account, which is free to create. I suggest using the same Discord username you normally use, because the sign-in format requires you to include it alongside your Player ID.
Your Player ID is a unique string of numbers and letters tied to your game account. You can find it in your profile menu. Look for the small icon in the top-left corner of the main screen, tap it, and your Player ID will be displayed near your username.
One common mistake I see is players confusing their display name with their actual Player ID. The display name is what other players see in chat.
The Player ID is a separate alphanumeric code that the game uses for identification. You need the ID, not the display name.
Step 1: Find Your Player ID in the Game
Open Sword x Staff and log into your account. Tap your profile icon in the upper-left corner of the main screen. Your Player ID will appear directly below your character name.
Write this ID down or copy it to your phone’s clipboard. You will need to paste it into Discord every day for three days. If you play on multiple servers, use the Player ID from the server where you want to receive the reward.
Step 2: Join the Official Discord Server
Go to the official Sword x Staff Discord server. The developers share the active invite link through their official social media channels, including X and Facebook. I found the current working link posted by the official account on the day the event started.
Once you join, verify your account if required. Some Discord servers ask new members to click a reaction button to unlock channels.
This is normal and takes about ten seconds. After verification, you will see a list of text channels on the left side of the screen.
Look for a channel dedicated to the sign-in event. It is usually named something like sign-in-event or chomusuke-claim.
The channel description will mention the 3-day reward and the KonoSuba collaboration. If you are unsure, scroll through the channel list and read the descriptions.
Step 3: Post Your Details in the Sign-In Channel
Click into the sign-in channel and post a message containing your Player ID and your Discord username. This is your first daily sign-in. You do not need to write anything fancy, just the two pieces of information in the correct format.
Wait a moment and confirm that your message appears in the channel. If it does not send, check your Discord permissions.
New members sometimes need to wait a few minutes before posting in event channels. This is a standard anti-spam measure and nothing to worry about.
Step 4: Repeat for 3 Consecutive Days
Return to the same Discord channel on the next two days and post your Player ID and Discord username again. You must sign in on three separate days in a row. The posts do not need to be at the exact same time, but they do need to happen on three distinct calendar days.
I set a phone reminder for the same hour each day to avoid forgetting. The entire process takes under two minutes once you have the Discord app open. Community members recommend posting in the morning so you do not miss the cutoff if your evening gets busy.
Keep an eye on the channel announcements. Moderators sometimes pin a message confirming which day the event is currently on.
If you see a day 2 announcement and you already posted twice, you are on track. If you only posted once, you need to catch up before the event ends.
Step 5: Claim Your Reward From In-Game Mail
After completing your third consecutive sign-in, the reward does not appear instantly. The developers deliver Chomusuke through the in-game mail system. Open your mail tab in Sword x Staff and look for a new message with the reward attached.
Delivery typically happens within 24 hours of your third post. I received mine about six hours after my final sign-in.
If you do not see it immediately, close the game completely and restart it. This forces the mail system to refresh and often makes the reward appear.
Once the mail arrives, tap the claim button and Chomusuke will be added to your Fantomon collection. You can then equip it from the companion menu.

Sign-In Format Example
Players often ask what the exact post should look like. The format is simple and there is no need to add extra text. Here is the template I used to claim my reward:
Player ID: ABC123456789
Discord Username: YourName#1234
Replace ABC123456789 with your actual Player ID and YourName#1234 with your Discord handle. If your Discord username does not include a discriminator because you have a newer account, just write your plain username. The moderators can match your account either way.
Do not add extra hashtags or emojis to the post. Some players decorate their messages with symbols, but the clean format is the safest option. It makes verification easier for the event organizers and reduces the chance of your post being missed.
Event Duration and Deadline
The Discord sign-in event is tied to the KonoSuba collaboration period. It is active during June 2026 while the crossover content is live. I do not have an exact end date, but collaboration events in this game typically run for two to three weeks.
The safest approach is to complete your three sign-in days as early as possible. Do not wait until the final day of the event because missing one day would lock you out of the reward.
If you are unsure whether the event is still active, check the pinned messages in the Discord sign-in channel. Moderators usually update the status when the event ends.
Once the collaboration concludes, the sign-in channel closes. After that, Chomusuke becomes unavailable unless the developers rerun the event in the future. If you want to learn about other limited-time resources in the game, our Dawnium farming guide covers a currency that is always in demand.
Troubleshooting Common Issues
Most sign-in problems are caused by posting in the wrong channel, using the wrong format, or missing the Player ID location. Here are the exact fixes for each issue that players have reported in community forums.
I Cannot Find My Player ID
Your Player ID lives in the profile menu. Tap the icon in the top-left corner of the main screen.
If you still do not see it, try restarting the game. A temporary UI glitch can sometimes hide profile information, and a restart fixes it.
If you play on an emulator, make sure the game is displaying at the correct resolution. Some emulators crop the top bar where the profile icon sits. Resize the window or switch to full screen to reveal the full interface.
My Sign-In Posts Are Not Counting
First, verify that you are posting in the correct channel. There are multiple channels in the Discord server, and posting in general chat does not count toward the event. Only the designated sign-in channel is tracked by the moderators.
Second, check that your post includes both your Player ID and your Discord username. Missing one piece of information will likely cause your entry to be skipped.
If you already posted an incomplete message, simply post again with the correct format. The moderators generally accept corrected entries.
I Missed One Day
Missing a day breaks the consecutive streak. According to community reports, the event requires three consecutive days with no gaps. If you missed a day, you will need to start the three-day cycle again from day one.
That said, if the event is still running and you have enough time left, you can complete the new three-day streak before the deadline. Calculate the remaining days and decide if you have enough calendar days left to finish the requirement.
My Reward Has Not Arrived
Wait at least 24 hours after your third post before assuming something went wrong. The rewards are sent in batches, and the timing depends on when the moderators process the lists. I received mine within six hours, but other players reported waiting up to a full day.
If 24 hours pass and nothing appears in your mail, double-check that you posted in the correct channel for all three days. Then send a polite message in the Discord help channel asking a moderator to verify your entries. Include your Player ID and the dates you posted so they can check quickly.
