On November 20th, the second legendary costume in the history of 'Seven Knights Re:BIRTH' (hereinafter SKRB) made its debut. Following Tae-o’s 'Judgment Moonlight', which raised eyebrows by introducing a gender-swapped spin-off universe, it is now Yeonhee’s turn to step onto the stage as an idol. To sweeten the deal, the official YouTube channel dropped the track 'The 7th Season I’ll Miss Someday' sung by Yeonhee, offering players an immersive experience that feels like a genuine idol debut. Let’s take a closer look at this dimension-hopping pop star.

How did Yeonhee become an idol?

In the lore of SKRB, Yeonhee is a dimension-hopping powerhouse. After inadvertently saving the world while just trying to find a quiet place to nap, she effectively becomes the administrator of dimensions in the final timeline. She’s famously fond of sleeping, pillows, blankets, and warm cocoa—a calm, laid-back personality that doesn't exactly scream 'K-pop idol'. So, how did this happen?

Honestly, compared to the gender-swapped Tae-o, Yeonhee’s debut actually makes a bit more sense. The point is a clever twist on her established lore as a dimension administrator; in another dimension, her sleepy, lethargic nature has been flipped entirely into a vibrant, high-energy idol persona. At least they didn't swap her gender this time, which is a relief.

There is extra content that lets you dive deep into Yeonhee’s new career. Her OST 'The 7th Season I’ll Miss Someday' has been added to the jukebox. You don’t need to pull for the costume to enjoy the track; it’s available to everyone. If you want to listen while you grind, just make sure to check out the BGM settings.

This is what a trans-dimensional idol looks like!

The in-game version of Idol Yeonhee is a proper pop star, almost unrecognizable from her usual self. Her design blends her classic aesthetic with trendy idol elements perfectly. From the two-tone hair and cropped tee to the mini-skirt, leggings, and sneakers, it’s a look that emphasizes an active, high-energy vibe. She’s also accompanied by rabbit-shaped orb drones—which we’re fairly certain are speakers or cameras—that assist in battle with futuristic effects.

In combat, she greets you with a classic idol standing pose. Honestly, holding that pose is probably the hardest part of the job. During basic attacks, she breaks the pose to reach out, while the drones fire sound waves. It’s definitely a speaker. When you use her first skill, 'Gesture of Destruction', she hugs the drone to unleash a massive sonic blast.

Her signature skill, 'End of Eternal Sleep', features Yeonhee striking various poses in front of a microphone. By the end of the animation, she hops onto a giant version of the orb drone, and her outfit shifts color—moving from a fancy blue palette to a striking red and black combo that screams hip-hop. It hints at the potential for future color-swapping skins, a popular trend in costumes these days.

A quick tip for those who use Yeonhee for fodder leveling: the skill animation for this idol costume is slightly shorter than the original. It’s a nice little efficiency gain for those repetitive grinding sessions.

Costume summoning with a much more practical value

Given the premium quality of this legendary costume, you’ll need a fair amount of rubies to secure it. You’ll be looking at up to 9 pulls, starting with a free one, with the cost increasing by 1,000 rubies per step. It caps at 6,000 rubies from the 7th pull onwards, totaling 33,000 rubies. It’s a hefty investment, so don’t rely on luck—plan for the worst-case scenario.

That said, the reward structure has improved significantly compared to the previous 'Judgment Moonlight' Tae-o banner. Back then, the special profile border and Live 2D portrait were part of the summon pool, but now they come bundled with the costume. In their place, you get 20 'Pet Wish Summon Tickets' and 40 'Star Fragments'. If you have the rubies, it’s a solid deal that nets you both a high-quality skin and some useful resources.

If you’re a beginner who hasn’t pulled Yeonhee yet or you’re considering an upgrade, you can put those extra resources to good use. To celebrate the release, a rate-up summon for Yeonhee is currently live. Coupled with the '0.5th Anniversary Summon' and the existing hero wish list feature, your chances of getting her are better than ever. Both the Yeonhee rate-up and the Idol Yeonhee costume summon are available from November 20th to December 4th at 8:59 AM.
