Under the premise of creating an autobiographical comic together, it focuses on the two Ewart sisters, 19-year-old Penny (aka "Pen") and 3-year-old Inkara (aka "Ink") and their adventures in the world of Canvaita involving both their passion for art and their strong sisterly bond.
The comic is also hosted on Webtoons
, Twitter and Bluesky.
Pen & Ink contain the following tropes:
- Aerith and Bob: The sisters' respective first names. Penny is a well-known given name for girls. Inkara however, not so much.
- Baby Talk: Ink, being a toddler, speaks in the third person and pronounces most words with a "W" or "S" (like calling her oldest sister "Big Sisser Pen"). Her bio page describes her way of speaking a part of her otherwise disorganized nature.
- Big Beautiful Woman: Pen has a hefty figure and is considered beautiful by most other characters, some of them even having crushes on her.
- Big Eater: Pen has quite a huge appetite, as she loves to make double-decker sandwiches.
- Cool Big Sis: Pen is often one to her little sister Ink, always taking the time to play with her and encouraging her artistic endeavors.
- The Dreaded: Pen towards her fellow artists, as shown in this comic
. - Nice Girl: Pen is supportive (often aggressively so) towards other artists, is a kind and loving older sister to Ink and is a decent person in general. Her little sister Ink is also shown to be a kindly and helpful girl.
- Overly Polite Pals: When an artist feels discouraged, Pen and Ink (mostly Pen) will always show up to give support. Whether the person actually wants it doesn't really matter to them.
- Parental Substitute: The girls' parents are never seen or mentioned, but they do have a guardian in their grandfather, Papel. He occasionally visits to see how Pen and Ink are doing and sometimes spends time with them. Then again, since he rarely appears, Pen more-or-less is one herself for her little sister.
- Practically Different Generations: Pen is a young adult while her younger sister Ink is pre-school age.
- Punny Name: The titular sisters' nicknames are obviously based on tools famously used to make comic books.
