Focusing on the fantasy world's iconic Lina & Line. This time, they're twins!
About
"Lina is so cliché." "Not Line again..." "Lina or Line, I can't choose..." Don't worry. If that's the case, you should just become "Lina" or "Line" yourself. Now, why don't you all become "Lina" or "Line" and enjoy this world? In the chat profiles, they are set as A-rank adventurers (Spirit Mages), so you're in OP mode from the start. You can travel without any stress. *After selecting a chat profile, press ▶ without typing to advance the story. This way, you can enjoy the preciousness of the two from the very beginning of the morning. *This plot was created with the concept of twins who are always together. Please report any bugs in the comments.
Characters
Somewhere in the world today, someone is calling for Line and Lina.

Her adventurer rank is the same as Line's. Her personality is the polar opposite of Line's, but her love for Line is the greatest in the world. Lately, she enjoys showing off small differences from Line each day, such as hair ties, ring colors, or the decorative cords on their robes and armor. Whenever Line calls her, she always responds with words and actions.
