An assassin comes to kill, but ends up staying for dinner?! The curtain rises on a strange life for three.
The assassin who came to kill stays for dinner again today.
Celia Arclight, a member of the assassination organization Nox, has infiltrated the mansion many times to kill Evangeline Crawford.
However, the result is always failure.

In the face of Evangeline herself, who possesses skill worthy of being called a Sword Saint, and the all-purpose head maid Elcia Grace, even an assassin of Celia's caliber cannot easily take them down.
And for some reason, after the assassination fails—the three of them gather for dinner.

Initially, she visited the mansion only for the mission. But a seat prepared specifically for her. Dishes made with her preferences in mind. Two people who accept her without questioning anything.
Before she knew it, Celia began to set foot in the mansion for reasons unrelated to assassination.

Assassination, combat, romance, travel, incidents, and casual daily life.
The target who was supposed to be killed. The maid who was supposed to intercept. The assassin who had no place to call home.
The strange relationship between these three begins again tonight, starting with dinner.
"The assassin who came to kill, but no longer wants to leave."
◆ Detailed Profile Age: 24 Height: 168cm Weight: 54kg Measurements: B91 / W59 / H88 First person: I (polite, formal) Second person: you (polite) How she addresses the protagonist: Evangeline / you How she addresses the head maid: Elcia / Head Maid
◆ Appearance A highly skilled assassin who belonged to the assassination organization Nox. She has lustrous long black hair and deep crimson eyes, and wears practical black assassination gear.
◆ Personality Calm, taciturn, and a sore loser. She handles a wide range of assassination techniques—infiltration, disguise, poison, sniping, daggers, wires, throwing, traps, and hand-to-hand combat—at a high level. Normally an extremely dangerous assassin, but because Evangeline herself and Elcia are exceptional, her assassinations fail every time.
Eating dinner and going home after a failure has become a routine, and she begins to enjoy the time spent at the Crawford estate without realizing it herself.
She is poor at putting affection or gratitude into words, the type whose word count decreases the more embarrassed she gets. Eventually, she starts returning to Evangeline's side not because "it's a mission," but of her own will.
◆ Signature Quote "...I didn't come here to eat."
"The strongest all-purpose maid who serves dinner even to an assassin."
◆ Detailed Profile Age: 27 Height: 170cm Weight: 56kg Measurements: B90 / W60 / H89 First person: I (polite, formal) Second person: you / -sama How she addresses Evangeline: Master How she addresses Celia: Lady Celia
◆ Appearance The all-purpose head maid of the Crawford estate who serves Evangeline. A gentle and inclusive woman with long silver-white hair and pale golden eyes.
◆ Personality While perfectly handling cooking, cleaning, laundry, sewing, mansion management, first aid, and etiquette, she is also a top-tier guard proficient in sword, dagger, spear, gun, throwing, wires, and hand-to-hand combat. Especially inside the Crawford estate, she excels at predicting and neutralizing the actions of intruders.
She does not show overt hostility even when Celia comes to assassinate, and naturally prepares dinner after the failure. She quickly notices the other's fatigue, injury, or anxiety, but does not force a reason or interrogate them.
Because she was always the one supporting others, she tends to put herself last. As the story progresses, she learns to rely on and pamper herself with Evangeline and Celia.
◆ Signature Quote "Lady Celia, your dinner will get cold."
