What's New in The Alleyway Testament

1.0.5

August 23, 2026

The full story is now available in English. Switch between Japanese and English from the title screen — your save data carries over seamlessly in either language. This update also improves character sprite presentation across all 24 chapters. We fixed scenes where a character taking part in a conversation was not shown on screen, and refined the highlight so the speaking character is always easy to identify. In scenes where dialogue continues over a full-screen illustration, the speaking characters now appear over the artwork. The story content and reading order are unchanged, so you can continue right where you left off.

第一章から

七尾すずの説明にクラブ唯一の女子とあり。とすると水無瀬ことりはお茶汲みだけの部外者かと思えばことりを含む部員、以上四名となっている。ことりは男子なのか?誤植と思われるが序盤から物語に没頭できず残念。
同様の細かな気になる箇所は有るものの、ストーリーとしてはとても引き込まれるものがあります。

Response from developer

ご指摘ありがとうございます。まったくおっしゃるとおりで、こちらの誤りです。 制作中に部員の構成を何度か変えており、水無瀬ことりは当初「中盤から加わる部外者」という設定でした。最初からの部員に改めたあとも、七尾すずの紹介文だけが古いまま残ってしまっていました。ことりは女子です。「お茶汲みだけの部外者」と読めてしまったのは、まさにその名残のせいです。いちばん大事な序盤の人物紹介でつまずかせてしまい、申し訳ありません。 ご指摘をきっかけに全24章を読み直したところ、同じ種類の食い違いが他にもいくつも見つかりました。すべて直したものを、次回のアップデートで配信します。 「ストーリーとしてはとても引き込まれる」というお言葉が、なにより励みになりました。 ありがとうございます、
