Mechanics and community lore
Medama / メダマ / 眼玉: the community Cobun page, accessed 16 October 2026, describes a Ratatan giving a Medama to a Chorus to create a Cobun. Chorus / コーラス / 音徒 (Ototo): fish-shaped creatures described by that same source, which places them throughout Redo (レド). These are attributed wiki descriptions, not an official Chinese glossary.
Ratakaruta: adventure upgrade cards. The December 2025 announcement introduced Duo cards with a one-Duo-per-run restriction, not a one-card total limit. Oath Level and Goddess Games: the official FAQ says Oath Level 1 or higher opens Episode 2 after the first clear, with higher levels for later episodes. Welcome Mode: solo difficulty assistance, unavailable in co-op.
Dekadon: a stronger World 3 boss form on the community wiki; see bosses. World 6: the later story world confirmed by v1.1.9, with the final boss in Episode 4. Fortrun: the spelling used in the 16 October announcement about planned customization, not a shipped feature with a release date. Crow: the character named in the v1.1.9 tutorial fixes; those notes do not establish the eye’s origin.

Questions
Where is Rataport?
啦嗒港 is the hub you return to. It is not a real-world place.
What is a Melodium?
奏具, the magic instrument. The character’s own ability is called a Ratatan Skill.
