The Soul Score... that is something not unlike the threads of fate which tell the story of a person's life from the minute they are born to the finale of death. Few people can see this score, even fewer can manipulate it.

After being hit by a car and nearly killed, Kyosuke Hibiki can see and hear this mysterious soul score. Soon after, he meets a girl named Tena, a "tuner" who is able to manipulate the score and remove discordant notes to bring it back into tune. Tena is determined to make Kyosuke her pet, but Kyosuke is none too fond of it. Yet, the two begin their dissonant duet...

S-senjou no Tena was published in English as Tena On S-string by Yen Press from August 4, 2009 to April 21, 2015. Yen Press published the 6th and 7th volume as a 2-in-1 omnibus labeled as Volume 6 and the final two volumes compiled as Volume 7.
