Summer Time Rendering: Another Horizon — English Localization Glossary (finalized for pasting)

The three code blocks below (Characters / Places / Terminology) are ready to copy-paste as-is into the translation prompt’s [PASTE YOUR GLOSSARY HERE] placeholder. Style decisions and judgment calls on ambiguous readings have already been made (see “Decisions made for you” at the bottom) so you don’t need to read Japanese to use this.

Everything was extracted directly from the game data (speaker names in developer_comments, chapter titles in original_files/json/FlowChartData.json, and tip titles in original_files/json/AppGameDataTipsData.json) — it’s a verified roster of what’s actually in the game, not a guess at what might be in it. The English spellings are Hepburn-romanization judgment calls (see notes below); they’re internally consistent and good enough to ship with.

One optional check: this game shares its cast/setting with the “サマータイムレンダ” (Summer Time Rendering) anime, which had an official English dub release (Disney+). If you happen to recognize any of these character names from that, feel free to swap in the spelling you remember — otherwise the ones below are perfectly fine to use as-is.

3. Recurring in-universe terminology

NOTE: AppGameDataTipsData (168 entries) is essentially the developers’ own in-game glossary of key concepts — translate it carefully and consistently, since these exact terms recur throughout the dialogue.

影 = Shadow(s)                          [central concept — capitalize as proper noun in-story]
影の病 = Shadow Sickness
影の能力 = Shadow's Ability / Power of the Shadow
観測者の力 = the Observer's Power
事象の地平線 = Event Horizon              [real physics term, used as a story concept]
過去への干渉 = Interference with the Past
御海送り = Umi-okuri (Sea Send-off)       [local ritual — consider keeping JA term + gloss on first use]
天沼矛 = Amenonuhoko                       [mythological spear, Japanese creation myth — keep as proper noun]
常世 = Tokoyo                              [mythological "eternal realm" — keep as proper noun + gloss]
ドッペルゲンガー = doppelgänger
カプグラ症候群 = Capgras syndrome           [real psychological condition]
惨劇の夜 = the Night of the Tragedy
正義の味方 = Hero of Justice / Champion of Justice

4. Decisions made for you (so you don’t have to call these yourself)

Honorifics (-san/-chan/-kun/-senpai): KEEP them. This is the prevailing convention in modern English visual-novel/anime localization — English-reading fans of this genre expect them, and dropping them erases relationship nuance (who’s being formal/familiar with whom) that the story relies on. Add to the prompt: “Preserve Japanese honorifics (-san, -chan, -kun, -senpai, etc.) in romanized form rather than translating or dropping them.”
Ellipses …… → single-character … (not ...). Keeps spacing/rhythm closer to the original and is the standard in professional VN localization. Tildes 〜 → ~.
Internal monologue vs. spoken dialogue: no special text formatting needed. The game engine already controls how these are displayed (different text boxes/styling); the translated string itself doesn’t need added markup like italics or quotation conventions.
Parenthetical character-state qualifiers (e.g. “（影シンペイ）” = “Shadow Shinpei”): translate them inline, exactly as shown in section 1 above — e.g. “Shinpei Ajiro (Shadow Shinpei)”. These only ever appear in developer_comments (translator/AI context — not shown on screen), so consistency there just keeps the AI from confusing which “version” of a character is speaking in a given scene.
Long vowels: ASCII only, no macrons. Don’t write Ryūnosuke / Sō / Seidō (Wikipedia/Disney+ house style); they don’t render reliably in the game font/UI. The rule: simplify the long vowel away (竜之介 → Ryunosuke, 銀次郎 → Ginjiro) unless dropping it leaves an ugly/confusing 1–2-letter name or collides with an English word — then keep the ou/uu form (菱形窓 → Sou, not “So”; 青銅 → Seidou). Apply this consistently to any new name with a long vowel.
Name spellings verified against the official release (Disney+ / Wikipedia / Fandom, cross-checked with the anime subs, 2026-06):
- ハイネ → Haine (was “Heine” — corrected everywhere, incl. the talker_013 name plate). Confirmed by both the official wiki and the subs.
- エリカ → Erika (was “Erica” — minor; unified across all lines).
- 小舟アラン → Alain (French spelling; was “Alan” — corrected everywhere, incl. the talker_012 / talker_012s name plates). Confirmed by both en.wikipedia and VNDB’s entry for this game.
- 小弓場かおり → Kaori Koyuba (was “Koyumiba”; 弓 read as “yu”, not “yumi”). Per VNDB, user-confirmed; talker_020 plate regenerated.

These are now baked into section 1’s formatting — you don’t need to do anything further with them other than tell the AI to follow the same conventions for any names/terms it encounters that aren’t in this list yet.
