Prologue: Mission Start!

19 year old Oguro Yuuya has been trained from a young age to be one the best if not THE best Shinobi alive in present Japan. Such title and recognition has him sent into very hazardous missions by the Japanese government itself!

One day, the Japanese government has sent him into a new mission, "Protect the Tsurumaki Family's only daughter along with her friends from any possible threat". Unbeknownst to him, this mission isn't as simple as it seems especially with a faction of unknown origins trying to wreck havoc.

Join Yuuya as what he thought of as a surprisingly straightforward mission ends up being the most wackiest yet?!
