Dengeki Bunko: Crossing Void

Dengeki Bunko: Crossing Void is a turn-based RPG mobile game that features characters from light novels published by Dengeki Bunko, including Durarara!! characters Celty Sturluson, Shizuo Heiwajima, and Izaya Orihara.

The game is currently only available in Chinese, and players must log in using a WeChat account.

Gameplay
The game offers both PVP (player versus player) and solo story mode.

In PVP mode, players must form teams of three characters and unleash their skills to win fights. The use of a skill can be bought with the players' points. Characters are divided into Main and Sub characters. Main characters have a basic attack, an active skill, a special skill, and a number of passive skills depending on their rarity. Passive skills can be unlocked through gameplay. Sub characters are the support. They have passive skills that benefit the main characters and can be unlocked through gameplay. They also have one active skill. Playable characters are ranked S, A, B, and C, with higher ranks holding more passive skill slots.

Main and Sub characters need to be matched by synergizing characters, thereby unlocking a crossing skill that the characters can perform together. Characters from the same series have more synergy than characters from different series. Higher cooperation can be reached between characters in solo story mode, a dating sim mechanic featuring Live2D animation that strengthens characters' relationships.
