Dr. Arno Crossword (クロスワード・アルノ博士, Kurosuwaado Aruno Hakase) is a character.
Plot EditHe first appeared in Episode 5. He explained how time travel works and parallel worlds. Because no other member from Raimon seemed to understand it, Yamana Akane simplified the explanation, as she likes science fiction.
He appeared another time in Episode 7. He stopped by to confirm that Gouenji wore a Time Bracelet and somehow knew him. He is trying to make some kind of antidote to save Endou Daisuke from the Chrone Stone.
In Episode 12, he appeared again and explained why Shindou couldn't Mixi Max with Oda Nobunaga: Nobunaga's power being too strong to be fused with Shindou, Crossword said Shindou had to train to become as strong as Nobunaga, and then to master Keshin Armed.
Arno appeared again in Episode 31, talking about Perfect Cascade. He also said that to Fei that the situation is worse, as El Dorado is now using their ultimate team. Later, he explained that knowing about Zanak Domain's failure against Raimon, El Dorado had previously passed the Time Paradox effects to Perfect Cascade, so Fei and the others would need to beat them.
- He has the habit to appear and disappear when it is not expected.
