Changes

Kyosuke appeared in many episodes of the first series. He and [[Shouko Marukura|his wife]] wanted their son [[Marucho]] to stop playing around and learn many tough subjects. Marucho did it all to make his parents happy until he started playing [[Bakugan]] and joined the [[Battle Brawlers|Brawlers]]. He appeared again with his wife saying goodbye to Marucho when he and the other Brawlers decided to go to a portal that leads to the center of [[Vestroia (Generation 1)|Vestroia]].

In ''[[Back In Sync]]'', he contacts Marucho and tells him to quit the Brawlers. He also knew about [[Dan Kuso|Dan]] and [[Drago (Dan Kuso)|Drago]] leaving, how the Brawlers are falling apart and how [[Bakugan Interspace]] has become more chaotic. He originally wanted Marucho to give up brawling and work for the [[Marukura Group]] in order to fix Interspace. However, when Marucho decides not to, he accepts Marucho's decision after watching Marucho's victory against [[Jack Punt]], saying how proud he is of his son.
