HOLY GRAIL ERIS GN (2025)

Connie is a viscount's daughter with little notable attributes besides her sincerity, so when she's suddenly framed for a crime she didn't commit, it seems like the end of the line for her-until the ghost of Scarlet Castiel, an infamous villainess who was executed ten years ago, swoops in and clears her name. In exchange, Connie resolves to solve the mystery behind Scarlet's untimely death...and in the process, uncovers a conspiracy that still haunts the present!  

The day after the fiasco at the aristocratic party, Scarlet Castiel demands her compensation for saving Connie's life: help her take revenge on those who orchestrated her execution! Despite her initial hesitation, the normally reserved Connie joins hands with the supposed villainess of the century to finally bring the truth to light!

 In their quest to uncover the truth behind Scarlett Castiel's death, Constance and Scarlett attend Emilia Godwin's soiree to fish for clues. Fishing in a sea of sharks is never easy, however, and their investigation is sidetracked when barbed insults escalate into an attack. And with Randolph Ulster popping up every which way they turn, finding answers is going to be much harder than they thought!

After becoming engaged to Randolf Ulster during Earl John Doe's Ball, Constance reaffirms her promise to help Scarlett-not for the sake of repaying her debt, but out of gratitude for her help with Pamela. Now, what awaits her at the Silent Ladies' Tea Party, hosted by none other than Deborah Darkian...?

Trust in Adelbide’s royal family is shaken, and the conniving Baron Camille Miller has a few tricks up his sleeve to restore their public image. He asks Connie to be the star in his scheme, but when she refuses, Camille begins to circulate rumors that her distant relative—the first Percival Grail—murdered Saint Anastasia. And yet something isn’t quite right… Can Scarlett and Connie uncover the true history before it’s too late?

On the way back from visiting the Bronson Company, Connie is nearly kidnapped but saved in the nick of time by Aldous. Realizing just how much danger she's in, she tries to keep Kate at a distance...but it's all for naught when Kate is taken and a threatening blackmail letter arrives! Connie leaps into action to save her friend, but she's not the only one on the move, as Amelia Hobbes and the merchant Vado both have their own plans...

After Kate's successful rescue, Randolph attempts to get to the bottom of Daeg Gallus's plot and the neighboring Faris's plans. Meanwhile, Connie remembers that she has Lily Orlamunde's key, the object that Daeg Gallus was searching for, so she pays a visit to Randolph to hand it over. But when Randolph's colleague Kyle witnesses their awkward exchange, he begins to suspect that their engagement might be nothing more than a sham...

According to Scarlett, during the attempted assassination of Crown Princess Cecilia, the earring that pinned the crime on Scarlett was switched out with a fake. And the most likely suspect to have made the fake earring is Scarlett's fan-Aisha Huxley. Connie heads to the Huxley mansion to hear what she has to say, and despite Aisha's best efforts to keep her secrets, she's driven into a corner by the girl-and-ghost duo. At last, the truth about Scarlett's execution ten years ago will be revealed, and the meaning behind Lily's cryptic message shall also come to light...

Connie has finally solved the mystery of Lily Orlamunde's key and discovered the true meaning of "the Holy Grail of Eris"-a military operation devised by Faris, their neighboring allied nation, to invade Adelbide. Now, the story rewinds to the past, allowing a glimpse into the life of the woman who left the cryptic message. From Lily's meeting with Scarlett, to her childhood with Crown Prince Enrique, to Scarlett's execution...just what did she come to discover? And what drove her to commit suicide?

Thanks to Deborah's machinations, Abigail, who was working to prove Aldous's innocence in the case of Aisha's murder, is arrested by the Royal Military Police as a material witness. Connie, feeling guilty for implicating Abigail and worried that she might be executed, heads to Folkvangr with Scarlett and Randolph to formulate a rescue plan. Will they succeed at stopping Abigail from meeting the same fate as Scarlett ten years prior…?

Connie learns from San and Eularia the shocking truth behind Prince Ulysses's kidnapping-that it's all an excuse for Faris to wage war against Adelbide. What's more, the same plan had been carried out ten years ago, and it was foiled only due to Scarlett Castiel's execution. But how? Randolph, who comes to the same conclusion, makes his way to the Castiel estate to question the duke. Will the truth behind Scarlett's demise be revealed at last…?

To fulfill Scarlett’s quest of revenge, Connie gives Duke Adolphus Castiel a mean slap—a slap that awakens many memories. He remembers the day he took in the last Farisian princess, Aliénore, as his wife; the day his wife put down her obedient mask and bared her fangs to him; the day she came to truly love Adolphus; and even the day of Scarlett’s execution. Using Connie as a medium, will Adolphus and his departed daughter finally be able to face each other and speak from the heart?
