Постер аниме Kessoku Band Gritty

A dramatic anime rock-band poster in a gritty splash-ink promotional style, featuring the four girls of Kessoku Band on stage in a single wide composition with dynamic concert energy. The background is a chaotic black concert backdrop filled with paint splatters, sparks, smoke, neon-like color streaks, and a huge rough white brush-lettered band name across the top reading {argument name="band name" default="KESSOKU BAND"}. In the upper left, add a large comic speech bubble with bold hand-drawn English text reading {argument name="speech bubble text" default="KESSOKU BAND WERE CRUSHING IT"}. Show exactly 4 band members standing shoulder to shoulder in performance poses, each wearing dark band T-shirts and casual stage outfits, with stylized colored lighting around them. On the far left is Yamada Ryo with short dark blue hair, holding a cream-colored bass guitar, calm expression, blue paint splash behind her, and her name displayed in Japanese and English: "山田リョウ" and "YAMADA RYO". Second from left is Ijichi Nijika with blonde twin ponytails, energetic pose with one hand raised in a peace sign, warm yellow splash behind her, a large red ribbon at the collar, and her name displayed as "伊地知虹夏" and "IJICHI NIJIKA". Behind the center area place a red drum kit with the band logo on the bass drum. Second from right is Kita Ikuyo with long vivid red hair, playing a blue electric guitar, red splash behind her, and her name displayed as "喜多郁代" and "KITA IKUYO". On the far right is Gotoh Hitori with long flowing pink hair, playing a black electric guitar, pink splash behind her, and her name displayed as "後藤ひとり" and "Gotoh Hitori". At the bottom left, place a huge hot-pink Japanese title in aggressive brush lettering reading "結束バンド", with smaller white Japanese tagline text beneath it. At the bottom right, add a diagonal hot-pink paint-stroke banner with bold black handwritten English slogan text reading {argument name="bottom slogan" default="LIVE IS OUR LIFE, LOUDER THAN YESTERDAY. STRONGER TOGETHER."}. Use a high-contrast manga poster aesthetic, saturated blue-yellow-red-pink accents for each girl, rough halftone texture, distressed paintbrush typography, explosive stage-light atmosphere, and polished anime character rendering. Keep the composition dense, edgy, and poster-like, as if for an official movie or concert key visual.
