Background

When he became older and his thoughts and his ideology about how the shinobi world is drafted changed, Kaba started talking to Shigeki that Tomo's training was wrong, and she should not think too many in the variables and algorithms and should act more on impulse, improvise and follow her emotions.

After minutes of arguing, Tomo and Kaba fought fiercely, and stopped only when Shigeki intervened, arresting the two into a slime trap.
