How to Get Ethan Mumen Rider for Free in Blood Strike

1. What Is the Ethan — Mumen Rider Skin?

The Ethan — Mumen Rider is a completely free Striker skin available during the Blood Strike x One-Punch Man collaboration (July 1–31, 2026). According to the official Blood Strike update page, it is obtained through the "Justice Enforcement" exploration event — a mission chain that requires active gameplay, not just logging in.

Mumen Rider (the "License-less Rider") is one of the most beloved characters from One-Punch Man — a C-Class hero with no superpowers who never gives up. The skin maps his green helmet, brown outfit, and iconic bicycle aesthetic onto Ethan, one of Blood Strike's Striker characters. Unlike the bright yellow Saitama skin, Mumen Rider's muted color palette actually provides a tactical advantage — you're harder to spot at long range compared to premium OPM skins.

2. Step-by-Step: How to Unlock Mumen Rider

The "Justice Enforcement" event is located under the Events tab in the Blood Strike main menu. Here's exactly what you need to do:

Step 1 — Open the Events Tab (July 1–31)
Navigate to the Events section and find the "Justice Enforcement" exploration event. This is separate from the daily login rewards and the gift distribution event.

Step 2 — Complete Daily and Weekly Event Missions
Missions typically include: play Battle Royale matches, achieve eliminations, survive to certain placement thresholds, and complete OPM-specific objectives. Missions may have daily lockouts — you cannot complete them all in one sitting. Spread your gameplay across the entire month.

Step 3 — Track Your Progress in the Reward Milestone Screen
The event has a progress tracker showing how close you are to the Mumen Rider skin. Check it regularly — the skin is typically the final milestone reward, meaning you need to complete the full mission chain to claim it.

Step 4 — Claim the Skin Before July 31
Once you've completed all missions, the Ethan — Mumen Rider skin will be available to claim from the event reward screen. Claim it immediately — do not wait. If July 31 passes without claiming, the skin is gone forever. Blood Strike anime collaboration skins have never returned after their event window.

Do NOT Cram Everything Into the Last Week: The event likely has daily mission limits. Players who wait until July 24–31 to start will find they cannot complete enough missions before the deadline. Start early and play consistently — even 20–30 minutes per day is enough to stay on track.

3. All Free OPM Rewards — What Else Can You Get?

The Mumen Rider skin is not the only free item in this event. Based on the official patch notes, here's everything you can claim without spending Gold:

Free Reward	Type	How to Get	Time Required
Ethan — Mumen Rider	Striker Skin	Complete "Justice Enforcement" mission chain	~2–3 weeks of consistent play
SKS — Mumen Rider	Weapon Skin	Cumulative 18-day login during July 1–31	18 days (just open the app daily)
Parachute — Saitama	Parachute Skin	Event missions (July 9–31); friend assists speed up progress	~1–2 weeks with friend help
OPM Sprays, Stickers, Emotes	Cosmetics	Free reward track from event missions	Earned alongside the Mumen Rider skin
Gold Rewards	Currency	Scattered throughout mission milestones	Earned passively while completing other objectives

Total F2P Value: One full Striker skin + one weapon skin + one parachute skin + Gold rewards + OPM cosmetics — all for zero Gold spent. The free track in this collaboration is unusually generous. Even if you never touch the gacha, you walk away with a complete Mumen Rider loadout.

4. Tips to Complete Missions Faster

Play Battle Royale (BR) matches — most missions track BR gameplay (eliminations, placement, survival time). Squad matches with friends are the most efficient — coordinated squads survive longer and get more eliminations.
Use friend assists for the Parachute missions — the July 9–31 gift distribution event has a mechanic where inviting friends accelerates progress. Team up with active squadmates to clear these missions significantly faster.
Log in daily even if you can't play — the 18-day cumulative login for the SKS weapon skin only requires opening the app. Claim your login reward in under 30 seconds and close the app if you're busy.
Check the Events tab every time you log in — mission objectives sometimes rotate or unlock in phases. If you don't check, you might miss a newly available mission and lose a day of progress.
Avoid hot-dropping if you're grinding survival missions — dying in the first 2 minutes wastes time. Land at edge-of-map locations, loot safely, and aim for top-20 finishes to clear survival-related objectives consistently.

5. Top Up Gold for Premium OPM Skins — Topuplist Blood Strike

While Mumen Rider, the SKS weapon skin, and the Saitama Parachute are all free, the premium OPM skins — Jack — Saitama, Nacho — Genos, Spear — Terrible Tornado, and M4A1 — Garou — require Gold through the gacha, Strike Pass, and Lucky Bag systems. Topuplist makes it affordable to expand your collection beyond the free track with competitive Gold rates and instant delivery.

Everything — free and paid — disappears on July 31, 2026. Top up your Gold at Topuplist before the heroes punch out for good.

6. Frequently Asked Questions (FAQ)

Q: Is the Ethan — Mumen Rider skin really free?

Yes — 100% free. Zero Gold, zero real money. You only need to complete the "Justice Enforcement" event missions during July 1–31, 2026. It is not locked behind any paywall, gacha, or premium pass.

Q: How long does it take to unlock the Mumen Rider skin?

Plan for 2–3 weeks of consistent play (20–30 minutes per day). The mission chain has daily limits — you cannot grind it all in a weekend. Players who start in the last week of July will likely not have enough time to complete all missions before the July 31 deadline.

Q: What happens if I miss a day of missions?

Missing a single day is not fatal — the event allows some flexibility. However, missing multiple days in a row compounds and may make the full mission chain impossible to complete. The SKS weapon skin specifically requires 18 cumulative login days — you cannot speed this up.

Q: Can I get the Mumen Rider skin after July 31?

No. Blood Strike anime collaboration skins have never returned after their event window — not BLEACH, not Tokyo Revengers, not Seven Deadly Sins. The One-Punch Man collab follows the same pattern. July 31 is the absolute final deadline.

Q: Is the Mumen Rider skin better than the Saitama skin?

Tactically, yes. Mumen Rider's muted green/brown color palette blends into Blood Strike's maps far better than Saitama's bright yellow outfit. The Saitama skin is flashier and more recognizable, but Mumen Rider is the better choice for competitive play — you're harder to spot at long range. And it's free.

Q: What other free One-Punch Man rewards can I get?

Three confirmed free items: (1) Ethan — Mumen Rider Striker skin (missions), (2) SKS — Mumen Rider weapon skin (18-day login), and (3) Parachute — Saitama (July 9–31 missions). Plus OPM sprays, stickers, emotes, and free Gold rewards from the mission track.

Q: Where can I get Gold if I want premium OPM skins too?

Gold can be purchased through the in-game shop, but for competitive pricing and instant delivery, Topuplist is the recommended platform. Their Blood Strike top-up page offers Gold packages with secure checkout — ideal if the free Mumen Rider skin inspires you to chase Saitama and Genos from the gacha before July 31.
