Sui Sui Iruka-Kun

Sui Sui Iruka-Kun is one of Lala's inventions.

This invention is based on a dolphin, but its personality is rough, therefore it stampedes when it is surfing.

Sui Sui means "smooth or swiftly" and Iruka means "dolphin" in Japansese.

This invention is also one of the few inventions for aquatic environment as Zabu Zabu Wave-Kun is also. It looks a mechanised dolphin with a saddle, handle at its head and Deviluke's symbol at its forehead. And it has artificial intelligence and it is used as aquatic transportation.

It only appears in the chapter 66 of To LOVE-Ru, Yui uses it for surfing on the sea of the beach as seemingly she doesn't know the means to swim and Lala Lends Yui this invention for enjoying with the others. But unfortunately, everything ends up in a shamaless situation and the invention never appears again since this appearance. Yui gets on this invention in the beach, when it goes roughly, Yui is frightened and then Rito attempts to stop this invention on the sea. But this invention already gets out of control and its eyes are turned angry, and it ends up to be out of control and jumping on the sea. Yui angers with Lala for its rough invention and then Rito falls in a faint and in vague consciousness.
