16:9 anime key-visual poster, Japanese anime style, dark ominous high-contrast horror-fantasy mood. In foreground, anime girl Victoria (scarlet hair, glowing ruby-red eyes) and white-haired red-eyed anime swordsman stand back to back, small in lower frame, looking up with fear. Looming HUGE in the dark background, one giant glowing sinister PURPLE eye with vertical slit pupil opening in a pitch-black cave, casting eerie violet light on the two heroes. Terrifying scale contrast, dramatic atmosphere, embers and mist. LARGE bold Russian hook text 'ОНО СЛЕДИТ ЗА НИМИ' in glowing eerie purple-white anime font with strong outline, readable on mobile. Small title bottom 'РУБИН И КЛИНОК'. Small badge 'СЕРИЯ 1'.
