Rockman DASH: 5tsu no Shima no Daibouken!

Rockman DASH: Itsutsu no Shima no Daibouken! (ロックマンDASH 5つの島の大冒険!) is a Japanese game from the Mega Man Legends series released in 2008 for mobile phones via the i-mode Internet service. The game has a total of five islands, each with seven areas to explore. Mega Man Volnutt and friends explore them in search of treasure and to uncover their secrets.

The graphics engine used in the game is similar to that used in Mega Man Legends and Mega Man Legends 2, however the game has a more polished look to it (less rough edges, sharper graphics, etc.). Most of the characters from the previous games have returned in this adventure, and there are many new and familiar enemies for Mega Man to face.

Release Information
The game was first released in February 2008 to Japanese public via the i-mode Internet service, a subscription service that requires a 315 Yen monthly fee (including taxes).

Story
In a world covered by endless water, people have a peaceful life in islands, and Diggers search ruins for Refractors, an energy source.

Mega Man and Roll Caskett were going to meet with Barrell Caskett, who is investigating an island. They test a new feature for the Flutter to increase its speed, but as it didn't work and damaged the engine, they need to land on Shiross Island to replace the Flutter's Refractor. Coincidentally, the Bonne family is also in the island, and they take over the city. After freeing the island, they continue they journey and the Flutter (not fully repaired) crashlanded in Pauran Island, an island said to have an cursed treasure. They search for parts to repair the Flutter's engine and fight against the Bonnes again.

While professor Barrell was visiting Ilux Island to investigate a possible "catastrophe", the police stayed on high alert to protect him. When Mega Man was looking for Barrell in the town, the policewoman Denise thinks he is a criminal attempting to cause harm to Barrell, and the police starts a hot pursuit to get him. After some fighting, Mega Man escapes through the town's sewers and must find Barrell to clear the misunderstanding.

In Urakoi Island, something is wrong with its ruins and large volcano, which may enter in eruption and block the sun with its ashes, affecting the environment drastically. Mega Man must explore the island's ruins to find a solution before it's too late. In the island, the mystery on how Refractors are made is partially revealed. Mega Man discovers ancient equipment that can create Refractors by using magma as energy, but for unknown reasons it can only produce low-grade Refractors.

When the Caskett family was returning home, they find one large ancient tower with three smaller towers nearby. Believing they may be related to the Mother Lode, they investigate the tower's ruins, which contains dangerous traps and fierce Reaverbots.
