Espresso

In spite of Espresso Cookie's best efforts, fate dictated that the two meet again in the Couldn't Care Less... And Yet Story. In this tale, Espresso Cookie expectedly avoids Madeleine Cookie for being "too conspicuous" and "spouting nonsense" while helping Kingdom Cookies construct a theater like those of the Republic. However, Madeleine Cookie's willingness to support his colleague in a related battle later on and even support his injured self on the way to safety instills Espresso Cookie with the slightest, tiniest bit of respect for his teammate. Espresso Cookie returns the favor and advocates for the paladin's wounds to be dressed before his own, indicating this newfound appreciation.

Presently, Espresso Cookie still harbors irritation towards and deep disagreement with Madeleine Cookie, but it is clear through his more amenable attitude in Cookie Odyssey that he tolerates the Knight Commander—if only just enough to not ignore him entirely anymore.

As a perfectionist, Espresso Cookie expects much both from others and himself. His workaholic attitude, combined with the fact he is quite literally made of coffee, usually keeps him awake for days, which frequently results in eventual fatigue. He's dedicated to perfecting Coffee Magic to the point of self-neglect, and intentionally drives students away from his class at the Parfaedia Institute so that he can spend more time on his research. Some students apply to his classes regardless, prompting Espresso Cookie to demand that they prove their dedication to the study before he will even acknowledge them. If he accepts them, he shows appreciation for their efforts, commending their skills genuine without hesitation. Espresso Cookie is of the same race as the Coffee Tribe of the Dark Cacao Kingdom, but hails from the same culture-rich Republic as Madeleine Cookie, the Crème Republic. Currently, it is unclear how he or his predecessors traveled there from the main continent. While Espresso Cookie's physical attributes and ingredients render him incredibly similar to the Coffee people, his lifestyle, activities, fashion, and so on almost seem to directly contrast against what is known to be typical of that culture. One possibility is that he was born in the Tribe's village and left at some point, or that he was born to other Coffee Tribe members who left the Tribe's village to live in the Republic.

Espresso Cookie despises Light Magic, which fuels part of his initial annoyance towards Madeleine Cookie. The social divide in the Crème Republic between the Upper City—the affluent district which worships the light, and the Lower City, Espresso Cookie's less wealthy hometown—is likely a factor in this.

Espresso Cookie is a serious, smug, and intellectual perfectionist, and does things with absolute precision. He speaks in a formal and calm accent and is often brief with his words, to the point of rudeness. His facial expression generally defaults to a composed and confident smile, but there are instances where he doesn't bother hiding his displeasure or exhaustion (such as when faced with a preventable failure or Head Icon Madeleine Cookie's running mouth). Despite this, he is capable of being polite in his conversations with other Cookies, and takes interest in their actions, like when he asked to read a report on Head Icon Alchemist Cookie's reagents. Due to his status as a well-respected mage, he has great pride in his expertise and Coffee Magic, though he remains open to outside suggestions as long as they are constructive. In his work, Espresso Cookie is highly meticulous and observant, refusing to allow any margin of error. According to Head Icon Latte Cookie, he hates co-research projects, which may extend to all tasks requiring cooperation; in the quest for the Soul Jam, he chose to separate from Madeleine Cookie instead of working together with him. However, he is still capable of teaming up if the situation demands; him carrying Madeleine Cookie back to the kingdom after both were injured during the Couldn't Care Less... And Yet Story shows his true colors as someone honorable and good at heart despite his personal distaste for his teammate.

The researcher's clothing fittingly sources dark academia fashion with hints of gothic or fantasy stylings. Espresso Cookie's outfit exists in two layers, the outermost being an elaborate mantle lined with steel and pinstripes.[2] The collar of the cape is large, round, and dramatic with curled corners, silhouetting the entirety of his head and having a lining with colors opposite of those in the cape's main lining. The outside of the garment is obsidian and adorned with an intricate display: among its decoration is the image of a glaring eye with sharp lashes and a pink pupil, and dark aubergine swatches of color forming more stripes and teardrop shapes through negative and positive space. The second layer of Espresso Cookie's outfit is a fitted, paneled onyx smock most resembling a graduation gown. While the majority of its hem is straight, its middle tabard extends further downwards in a sharp point. On his shoulders lies a stole in the same color as the main coat, its triangular ends ending at his waist and sporting warm brown and pink diamond details resembling peering eyes. A popped collar in a risotto color sits at the top of the stole and overlaps his chin. Adjacent to this is a rouge necktie with two diamond-shaped knots. His sleeves are long and cuffed at the end with dusty brown diamond cuff links. On his legs are a pair of charcoal slacks or tights with no discernible shoes. On more casual occasions, Espresso Cookie can be seen without his gown or his cape; in this case, he wears a paneled button-down with suspenders and dark pants. The colors of this shirt and pants are very similar to but not exactly the same as the colors of his gown's collar and of his legs respectively in his standard appearance, indicating that he may always be wearing this outfit underneath his gown in his playable look.

Espresso Cookie is a Cookie of average height and thin build with thickish legs. His color palette overall is very dark, moody, and brown, with even the lightest values ​​present being warm mid-tones, and his shape language largely consists of sharp triangles with some circular complements. At his base, his dough is a rich, dark sienna color while his smug eye is outlined with thick, long lashes in a Van Dyke brown. Espresso Cookie's iris takes a dull dusty rose color and lies beneath a sharp pupil, that being indicative of his Coffee Tribe origins and rendering his inner eye to overall resemble a coffee bean. Only the mage's left eye is ever visible with the other being hidden under hair. His thin eyebrows are lifted in amusement and his black smile is slight and confident. Additionally, he wears oversized glasses of metallic white gold whose lenses each resemble a coffee cup as seen from above. Espresso Cookie's hair is straight and colored in violet-toned ebony at its base. Its style is quite complex: most notably, a single large, curled bang swoops across the right of his face, completely enveloping his eye and coming to nearly his chin. It ends in a point away from his face and is peppered with mostly subtle highlights: from the outside to the inside, two are thick and warm tungsten, one is thin and black, and the final lines the inner edge of the hair in a creamy beige and ends in a prominent swirl at the top of his head. The rest of his hair is tightly combed back into curled tufts which radiate from the sides of his head. The back of his hair sports a large swirl similar to that on his bangs which radiates out from his scalp. Though much of its length is lofted into the hair, Espresso Cookie's hair is long enough to be styled into a ponytail.
