The Legendary Ino-Shika-Cho Naruto: Shippûden : Season 11 Episode 239

As Team Asuma considers the impending war, they encounter Kosuke Maruboshi who reminds them of the time that they rescued him while they were still genin. With this, Kosuke retells the tale of the time their fathers saved him during the Invasion of Konoha with their Formation Ino–Shika–Chō. Somewhat rattled by this story, Kosuke reminds them that great shinobi weren't made in a day. As the team contemplates everything, they decide to perfect their own formation, insisting that they'd be fine because they were not alone.
