Memorial Stone

The memorial stone is a monument in Konoha that lists all ninja that were KIA(Killed in Action). During Team 7's first bell test, Kakashi told Naruto about the monument( with Naruto saying he wants his name on the monument too) and told him that the  it contained the names of ninjas killed in action. Among the names are Obito Uchiha, Kakashi's teamate in Team Minato, and Hayate Gekko, the third proctor of the latest Chunin Exams. After he was killed by Baki just before the invasion of Konoha, his lover put some flowers on the monument to honour him. Also, Kakashi makes it a daily and routine habit to got to the monument in honour of his deceased teamate Obito Uchiha, which is the reason why he is late for everything.
