The Testament of Sister New Devil – Watch Order (2026 Edition)
| Order | Title | Format | Episodes / Length |
|---|---|---|---|
| 1 | The Testament of Sister New Devil | TV Season 1 | 12 episodes + OVA |
| 2 | The Testament of Sister New Devil BURST | TV Season 2 | 10 episodes + OVA |
| 3 | The Testament of Sister New Devil DEPARTURES | OVA (Final Story Arc) | ~60 minutes |
Why This Order Is Important

- 1️⃣ Season 1 MUST come first
This is non-negotiable.
Season 1 establishes:
- The devil–hero political conflict
- Basara’s pact system and power mechanics
- The emotional core between Basara and Mio
Without this foundation, Season 2’s conflicts won’t land properly. You’d miss character motivations and major relationship development.
- 2️⃣ BURST contains direct plot escalation
Season 2 is not a side story. It:
- Expands the demon world conflict
- Resolves arcs introduced in Season 1
- Deepens emotional stakes
Skipping Season 1 would make BURST confusing, especially regarding alliances and betrayals.
- 3️⃣ DEPARTURES contains spoilers for everything before it
This OVA acts as a sequel/epilogue.
If watched early, it spoils:
- Character growth outcomes
- Relationship progress
- Power developments
It works best as a “reward” after finishing both seasons.
Personal Viewing Experience

Watching it in this order genuinely enhances the emotional flow.
- Season 1 feels chaotic, intense, and slightly outrageous — in a fun way.
- BURST adds weight. The fights feel more meaningful because you’re already invested.
- DEPARTURES feels like a final curtain call. It doesn’t drastically change the story, but it gives satisfying character moments.
If you skip the OVAs, you won’t lose core plot understanding — but you will miss extra character bonding scenes that make the cast more lovable.

🇯🇵 Watching Japanese Streaming Services from Abroad? Here’s What You Need to Know!

- Most services are geo-locked to Japan.
→ You’ll need a Japanese IP address (VPN) to access most Japanese platforms like dAnime Store, U-NEXT, ABEMA, etc. - No English subtitles (usually).
→ Japanese services mainly cater to native speakers—subtitles are usually in Japanese only. - Payment requires Japanese methods.
→ Some platforms require a Japanese credit card, address, or phone number to sign up. - Amazon Prime Video JP is region-specific.
→ Even if you have Amazon Prime in your country, you’ll need a Japanese Prime account to watch JP-only titles. - Streaming schedules follow Japan Time (JST).

Some global services (like Netflix or Disney+) also offer Japanese-only exclusives, but availability and subtitles vary by region. Always check your local library!
“Answers from Japan” to Reddit Questions – FAQ
- Q“Is there going to be a Season 3? Isn’t the story unresolved?”
- A
- 🔥 What Reddit is saying
“season 3?”
“unresolved”
“hoping there was going to be more”→ After BURST, posts regularly appear from viewers who feel like “there has to be more.”
Overseas, there is often an assumption that:
If the story isn’t fully resolved → a sequel must be coming.There’s a high expectation that “unfinished threads = future production.”
- 🇯🇵 The Japanese Context
In Japan, there has been no confirmed announcement of a new anime production.
Within the Japanese fan context, the mindset is different.
Rather than “waiting for Season 3,” the focus tends to be on fully completing the existing series:Season 1 → BURST → DEPARTURES.
In Japan, it’s not unusual for:
“A manga to continue even if the anime does not.”Instead, the atmosphere often feels like:
- Two seasons + OVA = a solid stopping point
- Even without a sequel, it stands as a completed work of its era
Japanese fans are less likely to strongly demand “Season 3.”
There’s more of a feeling of:
“We’re grateful we even got this far.”
- Q“Where can I watch it? It’s not showing up on Crunchyroll.”
- A
- 🔥 What Reddit is saying
“where can I watch”
“isn’t showing up”
“adult content”→ Confusion when the title appears on the website but not in the app.
Overseas, this often turns into:
“If it’s not visible, is it a platform error?”
- 🇯🇵 The Japanese Context
In Japan, viewing order and platform availability are usually shared clearly.
The debate is less about “Why isn’t it showing up?”
and more about:
“Are you watching in the correct order?”There is also a very normalized distinction:
- Streaming version = censored
- Blu-ray version = uncensored
So when something isn’t available on streaming,
many people simply treat it as:
“That’s how it works.”Instead of asking, “Is the setting wrong?”
the conversation naturally shifts to:
“Should we just get the BD?”
- Q“Is there an uncut version? Where’s that missing scene?”
- A
- 🔥 What Reddit is saying
“uncut”
“uncensored”
“sauna scene”→ Posts asking why certain scenes are missing or altered.
Overseas, this topic often sparks stronger debate.
There’s noticeable attachment to finding the “uncut” version.
- 🇯🇵 The Japanese Context
In Japan, discussion culture tends to assume:
- TV broadcast version = censored by default
- Blu-ray version = the complete edition
So instead of arguing about censorship,
it becomes a question of:
Which format are you watching?Debates about censorship itself rarely escalate.
The focus remains more on story flow and character dynamics.
🎭 What Is The Testament of Sister New Devil About?
At its core, this is a story about protection and contracts.
Basara suddenly finds himself living with Mio — who turns out to be more than just a new step-sister — and is pulled into escalating supernatural conflicts.
It’s not just action. The emotional tension rises every time a contract is formed and relationships deepen.
There’s sweetness, but there’s also edge. A little danger. A little bite.
And once a scene hits that 尊い level… you might already be in the 沼 💜
