"Mochi Momo" is a starting-soon screen for a cute VTuber stream, in a soft pastel desktop style. A glossy pink-to-blue bubble name sits in a rounded retro window with a slim info bar below, and a large empty window on the right leaves room for the avatar, with clouds, hearts, sparkles and a ribbon bow around.

rendered as an idol name logo for a VTuber or idol channel: rounded, bubbly bold letters with soft round corners and big round counters, set with a light bounce so letters sit at slightly different heights and lean a little toward each other, every letter fully readable. The colour is flat vector logo art in layers and never changes the letter shapes: each letter face holds a smooth top-to-bottom two-colour pastel gradient (the brief's colours, otherwise pink to lavender); a white inner outline traces every letter; a thicker outer outline in a deeper shade of the main colour joins the whole word into one shape. Exactly two or three small decorations are built in — a star replacing the dot of an i, a tiny heart at one end, a sparkle beside one letter — never covering any letter. Flat colours with one soft white highlight per letter — no 3D extrusion, crystal, glow haze, characters or faces. Japanese idol and VTuber channel logo lettering: sweet and sparkly. Soft pastel streamer screen world, the kind of starting-soon screen a cute VTuber actually puts on stream. GRAPHIC LANGUAGE: the words sit in rounded retro computer windows and soft UI panels with tiny title bars, little dot buttons and a slim info bar; one large empty rounded window frame is left open beside them for the streamer's avatar; small stickers are scattered around the edges - hearts, four-point sparkles, stars, puffy clouds and a ribbon bow. LIGHT: soft even daylight, airy and bright, gentle bloom on highlights, no harsh shadows. COLOUR: cream white base with two pastel colours, baby pink and sky blue, plus small touches of lilac; lots of breathing space. TEXTURE: a faint grid-paper or polka-dot pattern on the background, lace-scalloped edges on one panel, a light paper grain. A 16:9 starting-soon stream screen: 'Mochi Momo' is the title in a rounded window on the left, 'STREAM STARTING SOON · 8PM JST' sits in the slim info bar below it, and an empty rounded avatar window takes the right side.
