Square Enix has kicked off its “Supergiant Blackboard Art Critical Hit Campaign” for Dragon Quest Heroes II: The Twin Kings and the Prophecy’s End ahead of the game’s release this Friday, May 27 in Japan.

The campaign sees the advertising space in the Tokyo Metro Marunochisen Shinjuku Station Metro Promenade filled with a giant blackboard art of Dragon Quest Heroes II, which took painter Renarena-san one month to finish.

Additionally, from now until May 24 at 23:59 JST, if tweets with the hashtag “#DQH2” reach over 5,000, on May 25 a “critical hit” by way of “Erdrick’s Sword Blackboard Erase” will be put into effect and wipe out all the monsters on the blackboard art.

Watch a video of the blackboard art creation below.

Dragon Quest Heroes II: The Twin Kings and the Prophecy’s End will be available for PlayStation 4, PlayStation 3, and PS Vita.

Thanks, Games Talk.
