Mio, a shapeshifting kitsune, battles an army of tanuki that can turn into anything in this side-scrolling bullet-hell STG. Enjoy the rush of clearing barrages with yojutsu (fox magic) and transformations to overwhelm enemies, alongside the slapstick antics of a colorful tanuki cast. Even with the move to horizontal scrolling, Outside's familiar accessibility remains intact.

The developer, Outside, is an indie circle with an ongoing history of making bullet-hell STGs. Its releases include Cosmo Dreamer in 2020, Like Dreamer in 2022, and REDNEG ALLSTARS SWING-BY EDITION in 2024. This new title switches from the vertical scrolling of its predecessors to horizontal scrolling. Following a playable showing at Tokyo Game Dungeon 9 in 2025 and a demo release, it launched in autumn 2026. It carries forward the systems that support beginners and the range of difficulty that challenges veterans, while using the horizontal format to showcase large characters and their shapeshifting antics.

Distance from enemies is the key to your offense. Moving closer strengthens your shots, fills the yojutsu gauge faster, and yields more score items. It feels satisfying to clear bullets with yojutsu, temporarily power up through transformation, push forward to collect items, and turn those gains into your next attack. With enough SP, an auto-shield also activates when you would take a hit, adding the pleasure of deciding whether to spend your gauge on offense or keep some in reserve for defense.

Above all, I strongly feel that this is designed to let even STG beginners play with confidence. You can select the difficulty for each stage, while the shop offers permanent upgrades to starting lives, firepower, gauge recovery, transformation duration, and more. It is welcome that even troublesome stages can be tackled through repeated attempts while developing Mio. Since Score Attack uses fixed stats, progression-based clears and skill-focused play can be enjoyed separately. Training mode also lets you adjust enemy patterns and speed, which should help you improve.

The anime-style girls are, above all, "big" - boobs included. Bosses make entertaining use of that scale through comical movements, expressions, and cut-ins, while even the regular enemies disguised as furniture and mechas keep things lively. Your small hitbox is displayed onscreen, and the colorful bullet patterns remain easy to distinguish. The melodic BGM and game homages scattered throughout also suit the festive chaos.

The main game is built around replaying five stages plus Extra, with an all-stage Trial mode and Boss Rush unlocked after clearing it. Since upgrades and bullet clearing let you power through, players who want to pursue precise dodging may find higher difficulties or fixed-stat challenges a better fit. It is a title worth recommending both to those who want a casual introduction to bullet-hell STGs and to those who enjoy repeating short runs to improve their scores.

"Mio and the other cuties bring such wonderfully big boobs to this horizontal STG!"

化けキツネのミオが、何にでも化けるタヌキ軍団と戦う横スクロール弾幕STGだ。妖術と変化で弾幕を消しながら敵を押し切る爽快感と、個性豊かなタヌキたちのドタバタ劇を楽しめる。横スクロールになっても、あうとさいどらしい遊びやすさは健在だ。

開発元の「あうとさいど」は、弾幕STGを継続して手がけてきたインディーサークル。2020年の『コスモドリーマー』、2022年の『ライクドリーマー』、2024年の『REDNEG ALLSTARS SWING-BY EDITION』と作品を重ねてきた。本作は従来の縦スクロールから横スクロールへ転換した新作で、2025年の東京ゲームダンジョン9での試遊出展や体験版公開を経て、2026年秋に発売された。初心者を支える仕組みと熟練者が挑める難度の幅を受け継ぎ、大きなキャラクターの変化芸を横画面で見せる作品となっている。

攻め方の鍵は敵との距離にある。近づくほどショットが強くなり、妖術のゲージも早くたまり、得点アイテムも多く得られる。弾を消す妖術と一定時間強くなる変化を使い、前へ出て稼ぎ、次の攻撃へつなぐ流れが気持ちいい。SPが一定量あれば被弾時にオートシールドも発動するため、ゲージを攻撃に使うか、防御用に残すかを考える楽しみもある。

本作はとにかくSTG初心者でも安心して遊べる設計になっていると強く感じる。ステージごとに難易度を選べ、ショップでは初期残機や火力、ゲージ回収率、変化の持続時間などを永続強化できる。苦手な面も、挑戦を重ねてミオを育てながら突破を目指せるのがありがたい。スコアアタックは固定性能で競うため、育成を楽しむ攻略と腕を磨く遊びを分けられる。練習モードで敵のパターンや速度を調整できる点も、上達の助けになるだろう。

アニメ調の女の子たちはおっぱいも含めてとにかく「おっきい」。大きさを生かしたボスのコミカルな動きや表情、カットインが楽しく、家具やメカに化けた雑魚たちまで賑やかだ。小さな当たり判定は画面に表示され、カラフルな弾幕も見分けやすい。メロディのはっきりしたBGMや随所にあるゲームへのオマージュも、お祭り騒ぎの気分に合っている。

本編は5面＋Extraを繰り返し遊ぶ構成で、クリア後には全ステージ通しのトライアルやボスラッシュも開放される。強化と弾消しで押し切れるぶん、精密な回避を追求したい人は高難度や固定性能での挑戦が合いそうだ。気軽に弾幕STGへ触れたい人にも、短い攻略を重ねて得点を伸ばしたい人にも勧められる一作といえる。

Fox Flare Night is Peak あうとさいど and the developers should be awarded the Nobel STG Prize for their outstanding contributions to the genre these past few years.

it's a great game, but these unlocks are just too much. i just beat expert trial score attack, and it unlocked a LOCKED nightmare mode. i guess it wants me to go back and do individual or story mode stages, im stuck guessing what the game actually wants me to do to unlock the higher difficulty stuff, so i think ill just play another game instead of guessing...
