Toaru Majutsu no Index (Mobile MMO)

Toaru Majutsu no Index (《魔法禁书目录》) is a   based on the Toaru Majutsu no Index universe. It was developed by  with supervision from Kadokawa and released for iOS on August 31, 2017 as well as Android devices on September 7, 2017. The game also has support for emulators as well as a official emulator by NetEase so players can play it on PC for now if they wish, and a dedicated PC version of the game is in development.

Story
The game primarily adapts the story of the Toaru Majutsu no Index light novels, focusing on the adventures of Kamijou Touma, a Level 0 esper wielding the Imagine Breaker, in the ongoing conflict between Magic and Science.

Gameplay
Toaru Majutsu no Index is composed of real-time combat elements combined with instance-based gameplay and world events that gives rewards to participants. Players control a single character at a time, and receive Touma and Stiyl as starter characters. Over time, more characters can be unlocked by playing the Pachinko minigame or otherwise acquiring 10 character-specific USBs of a desired character.

Each character has its own skills and characteristics. Aside from basic movement most characters can perform a Light Combo, Heavy Combo, Combo Skills, Jump and Sprint as well as up to three skills that consume Ability Power, a resource that is generated from successful attacks and combos. However some characters have exceptions, such as Agnese having only two skills but having many combo skills and the ability to negate defense and Awaki having no sprint/dash and in return has the ability to teleport her opponents. Other characters, like Index Librorum Prohibitorum and Kazakiri Hyouka, also have a Transformation mechanic, allowing them to take an alternate form in combat. Each character can equip cards that can boost specific stats, and can be customized by equipping skins that change their appearance.

In-game missions have a variety of objectives such as sneaking past Anti-Skill, fighting off waves of enemies, as well as boss fights and defeat all foes. In some game modes, players can use two other characters to switch between or call down for help.

Story Mode
The player must play through the original story of Toaru Majutsu no Index and Toaru Kagaku no Railgun. Even though it features voice acting similar to the anime, the game takes more of a focus from the novels, such as featuring the Dummy in OT2 and having to fight Kanzaki in Angel Fall due to the misunderstanding. Currently players can play all the way to Volume 14 with Volume 15 being released soon.

Open World
Players can explore Academy City and interact with various characters from the series (as NPCs) and other players, with things to run around and do such as buying food for Index or causing trouble around the city and catching the attention of Judgment and eventually Anti-Skill or simply hanging out with others in the open bath.

Boss Rush
After a player completes a volume they unlock a mission in a separate mode where they fight the enemies as well as bosses that they have encountered in one go.

Player vs Player
There are several methods of PvP with other players, such as fighting player-made NPC teams or fighting actual people in 1v1s or teaming up with others in 3v3s, featuring a leaderboard, reward and ranking system for competitive play.

Co-Op
Players can create parties to tackle specialized Co-Op missions at various locations, where players team up to tackle various bosses and enemies such as Anti-Skill, Skill Out and Ice Golems.

Dating
Players can form relationships with various characters wtihin Academy City, giving them gifts and taking them out for dates. Doing so unlocks a store for each character that gives special items and cards.

Battle Royale
A total of 30 players will be teleported to an island called Kawanoshima, each player is equipped with a collar that loses energy when they are out of the circle, when the collar reaches zero they start to lose health and must recharge it. In this gamemode every player is forced to be the same level and also can ultize various items for benefits such as a throwing item for combat or cake that increases your speed.

Sisters Dodge
One of the minigames, players are placed in a field with several Sisters, and must live until time runs out or defeat them all.

Robot Beat Down
One of the minigames, players are sent into a mission where all they need to do is beat up Security Robots and a giant variation.

Development
The game was made originally to act as a gift of gratitude to the fans of the franchise for the 10th anniversary of the anime series (on 2018) alongside the third season of the anime. Because of this, the head developers were already aware of the upcoming announcement, but limited the information to a number of key persons, with some informed only of an independent game based on Index instead of a joint project. The game received aid from those who worked on the anime in the aspects of art, post production, and audio (such as voice actors and music). The game aims to be as accurate to the franchise as possible, allowing the game to act as a standalone adaptation of the light novel series alongside the manga and anime.

Collaborations
The game entered a collaboration with the Senran Kagura: Estival Versus video game for the PlayStation 4 and PlayStation Vita consoles and the PC. Ten characters from the video game (Miyabi, Hibiki, Murasaki, Imu, Ryobi, Ryona, Homura, Yomi, Hikage, Mirai, Haruka) will be available as cards which can be equipped to characters for bonuses, Miyabi and Yumi will be available as a playable character. Events related to the collaboration will start on November 14, 2017, Miyabi herself will be available November 24, 2017 and Yumi will be released in Spring 2018.

Adol Christin, the main character of the Ys role-playing video game series, is also confirmed as a playable character.
