I love translation quirks like this.

There’s a game series called Shin Megami Tensei. It’s often likened to Pokémon for having a similar monster recruitment and battle focus. The spinoff series Persona is quite popular worldwide.

Anyway, SMT has a few stat buff/debuff effects. These differ from game to game, but the base three are Raku, Taru, and Suku. Add the suffix -kaja or -nda to denote a buff or debuff.

Most games have an ability that boosts all three at once, usually called “Lustre Candy” in English. The Japanese name for the skill is ラスタキャンディ, RaSuTa Kyandi.

They’ve taken the initial syllable of each buff, and it also happens to map perfectly onto how you’d spell “Lustre” using kana.

Some games have more of these buff skills. IMAGINE split them based on if they affected physical/magical attack/defence, so it had like five rather than the usual three.

The German translation is Sonderbonbon which is Special candy (or special bonbon).
