In this incident it's two-for-one?
The still-ongoing influence of the urban legends has brought about a new incident.
In this incident two people are one!? In that case, we'll have to resolve it together!
Create the baddest pair using Perfect Possession!
This is an incident where one person will spontaneously change places with somebody else, called "Perfect Possession".
The playable characters are paired up as "Master" and "Slave", and you can manipulate this designation at will.
The player will choose a pair of "Master" and "Slave", and will fight together while switching between each other as a danmaku tag battle.
A Slave can lend the Master her power, occasionally pull her out of a tough spot, and be disposed in times of emergency. Such duels of love, friendship and exploitation will soon unfold.
Note, it isn't particularly clear whether the phrasing for "choose a pair of Master and Slave" implies choosing individually or as a group, and translated it to mimic that ambiguity.
