- Takeshi Tsuruno is a fan of Ultraman 80, having watched the series in his childhood and once claiming that 80 would appear in Great Decisive Battle! The Super 8 Ultra Brothers before Hiroshi Nagano, Daigo Madoka's actor and Ultraman Tiga's voice actor at the time, corrected him.
- The original concept behind Shin Asuka is to have him as a baseball player, but this was less focused due to Takeshi having intermediate experience as a baseball player.
- The reason why his name "Tsuruno" was made into Hiragana was that he has difficulty writing Kanji. His real name is sometimes written as "Tsuruno". His uncle is an illustrator named Hisao Tsuruno. He professed to be a Christian with Antonio's baptismal name.
- The reason why Takeshi entered the entertainment industry was that he enjoys television and loves being conspicuous. Takeshi was a big fan of Chiemi Hori and the Onyanko Club. One of his classmates was on television once as a child, which inspired Takeshi.
- When Takeshi auditioned for Dyna, director Kazuya Konaka felt a strong impact from the goodness and brightness of Takeshi.
- Takeshi is a toy collector in his real life and had mentioned being a fan of Saint Seiya and the original 1979 Mobile Suit Gundam anime. He also kept the toys but unfortunately, some of them broke after he lent it to his eldest son for him to play with. In spite of that, he had also planned for buying replacements for the aforementioned sets.
