The official Diabolik Lovers Grand Edition on the Nintendo Switch was only released in Japanese. If you download a raw, untranslated NSP file, the game will be entirely in Japanese.
Beyond the legal and ethical issues, downloading and installing pirated "NSP" files carries serious, often hidden, dangers.
Downloading pirated content denies the developers (Rejet) and publishers (Idea Factory/Idea Factory International) the revenue they need to create future games.
A: Extremely unlikely. But you risk device malware, Nintendo bans, or a lawsuit if you upload. Most fans simply import the game.

Players can also download the game for free using a Nintendo Switch NSP file. However, this method requires some technical expertise and may not be suitable for all players. Additionally, players should be aware that downloading copyrighted content without permission is illegal and can result in severe penalties.
This is a painful, often-overlooked consequence. The developer of Diabolik Lovers , Rejet, is a relatively small company. There is a widespread belief that one reason Rejet has never officially localized the Diabolik Lovers games for Western audiences is due to a fear of piracy in foreign markets. By downloading a pirated version, you are reinforcing that fear and actively disincentivizing the company from ever bringing the series to English-speaking fans legally. You are quite literally stealing potential revenue from the creators.
