Sega’s mobile RPG Chain Chronicle 3（チェインクロニクル３）and Atlus’ PS3/PS4 title Persona 5（ペルソナ5）previously announced a crossover project without revealing much. Today (6th January, 2017), the official crossover website finally discloses two Twitter events and some crossover-exclusive characters.
The first Twitter event is a retweet reward. The crossover’s official twitter (@PirikaChro) will have a specific tweet for participants to retweet. Chain Chronicle players can receive a SR character Morgana（怪盗団の先導役 モナ）if the number of retweet exceeds 5,000.
3,000RT – Prysma（精霊石）x1
4,000RT – Growth Arcana V（成長アルカナV）x5
5,000RT – SR Morgana（怪盗団の先導役 モナ）x 1
To participate in the second event, players have to post a tweet with the hashtag #P5xチェンクロ. Three players will then be chosen randomly and given a poster signed by Persona 5 character designer Shigenori Soejima（副島成記）and Chain Chronicle producer Jun Matsunaga（松永純）.
The crossover characters have been revealed on the official website.
