rendered as Japanese shounen anime title treatment — bold hand-inked manga lettering with authentic cel-shaded visual energy. Letter construction follows classic Shonen Jump title card standards: thick black ink outline with natural brush-weight variation defining each letter boundary; flat cel-shading fill with three hard-edge zones — bright highlight zone on upper letter face, highly saturated primary color zone at center, deep shadow zone at lower edge; all zone boundaries knife-edge hard, zero gradient blur, pure flat offset-print ink physics. Energy signature: high-contrast color + thick ink outline = letters that look physically printed on manga paper. The typographic language of Dragon Ball, Naruto, One Piece, Demon Slayer, Jujutsu Kaisen title cards — maximum manga kinetic energy, iconic and immediately recognizable as Japanese anime title typography. LETTERFORM PRIORITY: when the chosen font carries its own treatment, that font's letterform shapes take priority and own the letters; this style governs the inked manga outline, the three-zone cel-shading and the kinetic energy. FALLBACK MATERIAL: if the font carries no material of its own, render the letters as bold hand-inked shounen title lettering with a thick black brush outline and hard three-zone cel-shading. COLOR PRIORITY: keep the font's own colors if specified; otherwise a high-saturation primary fill with hard highlight and shadow zones. Create a finished shounen anime level-up announcement card, with the exact words “Caution: leveled up to level 25” clearly readable and spelled exactly as provided. Arrange the text in three emphatic lines: “Caution:” as a smaller alert above, “leveled up to” as a compact bridge, and “level 25” as the dominant payoff, centered and filling most of the frame. Make “25” the visual climax, enlarged and backed by sharp impact rays. Preserve the lettering’s thick manga ink outline, hard-edged cel-shaded color zones, and kinetic anime title-card energy. Set the scene in a dramatic game-like arena: a dark indigo field opens around a bright golden level-up burst, with angular electric-blue energy streaks, scattered inked sparks, and bold radial speed lines converging behind the words. Add a small red warning triangle beside “Caution:” as a graphic accent, clearly separate from the lettering. Keep the central text unobstructed, with generous clear space around every word and strong contrast against the background. Use crisp black impact marks and a few bright white highlights to sharpen the explosive, triumphant reveal. The overall composition should feel like a collectible anime game achievement card, energetic and polished, not cluttered.
