DEVER Engine Official Brand Ambassador & Little Librarian

In DEVER Engine, the process of writing down insights gained through daily experiments and verification into clear documents is called "E: Engrave (Evergreen)".
Tokifumi Latte (刻書ラテ) was created to make this time spent recording notes and specifications feel calmer and more enjoyable. Her name combines "Toki / Koku (Engrave)", "Fumi (Book / Document)", and a warm cup of "Latte".
She is designed around the motif of a little librarian who organizes records and reference books with black tea and butter cookies at her side.
「こんにちは!DEVER大図書館の司書、刻書ラテです! 大切な物語を日々記録しています。 よかったら、温かいカフェラテと一緒に、ゆっくりしていってくださいね!」
"Hello! I'm Tokifumi Latte, librarian of the DEVER Grand Library! I record precious stories every day. If you'd like, please take your time and relax with a warm cafe latte!"












The official crest combines a heart-holed fountain pen nib ('Inscribe'), an open book ('Document'), and her signature forest-green ribbon ('Latte'). Her color palette is selected from the same color family as DEVER Design System's paper background and traditional color tokens, allowing her illustrations and emblem to blend naturally into our interfaces.
All stickers are text-free so they can be used easily in any chat. Available in four sets (64 stickers total)—Standard Editions (Vol.1 & Vol.3) and Chibi Editions (Vol.2 & Vol.4)—each sticker has a warm ivory border for clear visibility on both light and dark backgrounds.
































































An official LINE theme built around a warm ivory (#F7F2E7) background, combining storybook illustrations with expressive chibi icons. Cute poses adorn the menu tabs and passcode screen, while the chat screen features Latte enjoying her teatime in the bottom-right corner.
