Changes

Runo helps her parents run their family business, and when [[Alice Gehabich]] comes to visit, she helps Runo's family with their restaurant, which leads to Runo becoming jealous as boys came just to see her. But after she comes home from the Doom Dimension a group of boys are happy to see her. She has a severe crush on [[Dan Kuso]], but she won't admit her love for him. Still, when [[Dan Kuso|Dan]] is acting inappropriately, Runo does not hesitate to get annoyed. She reached 6th in the rankings.

When she arrives at the [[Doom Dimension]] and is being tested by [[Lars Lion]] she uses a younger, [[Illusionary Dan]] to brawl with Runo. It took Runo a while to realize that it was [[Dan]] since this was the first kid Runo met when she moved here but she never found out his name. It is shown she is not good at batting in baseball, but is a very good thrower, making younger Dan's hand hurt when she threw it at him. She learned through this that she needed to listen to her friends more and not to be so stubborn, which made [[Tigrerra]] evolve into [[Blade Tigrerra]] and defeat Lars Lion and Younger Dan. At the moment, Runo was with [[Apollonir]] when he challenged Drago for his test he was found by Dan when he pushed her down and  took of her mask,She had used two [[Mock Dragonoid]]s for that battle. At the moment, Runo, ranked sixth, battled [[Dan Kuso|Dan]] to help Drago further evolve. [[Shun Kazami|Shun]] was originally going to battle him before but [[Tigrerra]] wanted to brawl Drago first, to which everyone was okay with.

When the Brawlers were in [[Vestroia]], Runo, [[Dan Kuso|Dan]], and [[Julie]] were challenged to a race to the gate to the next world by stayed behind in the race to slow down the hybrids so [[Dan Kuso|Dan]] could win the race since [[Drago]] was the strongest Bakugan they had. She and [[Tigrerra]] were then able to defeat [[Rabeeder]] by using '''Velocity Fang'''.

This causes a great trouble to the [[Resistance]], as they, although still willingly, had to help her and due to this, was separated as [[Dan]], [[Mira Fermin|Mira]], and [[Baron]] having to go to Earth, and [[Shun Kazami|Shun]], [[Marucho]], and [[Ace Grit|Ace]] stayed behind in [[New Vestroia]]. This one action of her has caused the Brawlers to have lots of difficulties in taking [[Beta City]] where they're supposed to win quite easily.

When [[Dan]], Runo, [[Baron]], and [[Mira Fermin|Mira]] go through the portal to Earth, [[Spectra]], [[Gus]], and [[Lync]] follow them. [[Spectra]] proceeds to kidnap Runo, only to give her back to [[Dan Kuso|Dan]], having kidnapped her to make [[Dan Kuso|Dan]] follow him. After [[Dan]] and the other's learn the Dimensional Transporter needed to be fixed, Runo and [[Julie]] accompanied [[Dan Kuso|Dan]], [[Mira]], and [[Baron]] to back to their home. During the time [[Dan Kuso|Dan]] was back he and Runo showed how much they matured from the last series as they didn't fight that much but when they did they would end up laughing in the end. She gets ready to go back to New Vestroia with Dan in episode 19, but then has to stay on Earth as she needed a [[Gauntlet]] in order to go through [[Michael Gehabich|Dr. Michael]]'s dimensional transporter. She gets really upset by this but [[Dan Kuso|Dan]] promises he'll be back. At the end of arc 1 she got [[Blade Tigrerra]] back. When the Resistance became stranded on Earth, Baron once teased her about her baby pictures all over her parent's restaurant, however, she gets even by dragging Baron by the ear and stuffing him in the trash.

In ''[[Six Degrees of Destruction]]'', [[Mira Fermin|Mira]] returns and gives Runo, [[Julie]], and [[Alice]] Gauntlets.

In ''[[Earth Invaders]]'', after she mishears [[Dan Kuso|Dan]] and thinks he insulted her brawling skills, Runo goes off on her own looking for the [[Vexos]]. [[Mira Fermin|Mira]] follows her to get her to come back but they are soon discovered and battle against [[Mylene]] and [[Lync]]. Runo was able to defeat [[Lync]], but her and [[Mira Fermin|Mira]] were soon defeated by [[Mylene]], having [[Magma Wilda]] lose the [[Subterra]] energy. After the Resistance were thinking of how to get to Mother Palace to defeat the [[Vexos]] Runo comes to [[Dan Kuso|Dan]] to let him know that dinner is ready right when [[Spectra]] transported [[Dan Kuso|Dan]] and [[Drago]] to his ship. After [[Dan]] defeated [[Spectra]] he transported the [[Resistance]] members who have or had an [[attribute]] energy to come with him. This left Runo angry as she wanted to help out, but prayed that [[Dan Kuso|Dan]] would be careful.

In ''[[Enemy Infiltration]]'', she was told by [[Dan Kuso|Dan]] to stay in the HQ while the Brawlers go to Wiseman's hideout.

In ''[[Doom Dimension Throwdown]]'', she and [[Mira Fermin|Mira]] attempt to go to [[Volcano Island]] to search Dan and the others, and [[Julie]] wants to join them, but before they even have a chance to leave, they die due to [[Mechtavius Destroyer]] destroying [[Bakugan City]]. Because the Brawlers went through the [[Current of Time]] in ''[[Blast From the Past]]'', this event was reversed. They were revived in ''[[Beginning of the End]]''.
