In order to help Professor Kouzuki fulfil her plans for Alternative IV, Takeru partakes in an experiment designed to send him back to his home world.
I'm back in my old world!
!عدت لعالمي السابق
Ich bin wieder hier!
In der alten Welt!
¡Regresé! ¡Es mi viejo mundo!
¡He vuelto! ¡Es mi viejo mundo!
Je suis rentré !
Sono tornato nel mio vecchio mondo!
Eu voltei! Voltei ao meu mundo!
Я вернулся! Я в моём мире!
