He was scared and shocked that his team mates have died right in front of his eyes. Mako was shot by Nanashi Renjuu, Chiaki was rope neck and Genta take the whole blow by protecting Kotoha. "Tono-same should have died a long time ago. S-A-Y-O-N-A-R-A!" Akumaro said as he slash Takeru into half. "TONO!" Ryunosuke screamed. As Akumaro leaves, he rushed to Takeru to find out he's alright. "Ryunosuke..." Takeru muttered. "Tono?" Ryunosuke got confused after hearing him. "I want you to go and protect the other city with Kotoha. Take another identity for yourself." he said right before he died in Ryunosuke's arms. "TONO!" he cried as Kotoha comforting him who is also crying. "Someday, I will get my revenge on Akumaro for killing Tono-tachi." he whispered.
Ryunosuke woke up from his nightmare and found himself in Titans tower inside his room. "Tono, Mako, Chiaki, Genta... I'm sorry." he muttered as tears coming out from his eyes. "Ryu-chan?" someone asked. "Ahim... come in." he said. After the death of the Shinkengers, Ryunosuke later found out that Kotoha leaving the Shiba house to focus on the other team on her own. Ryunosuke later move to Jump City alone until he was found out by the other members of different team of Super Sentai. "Are you still having a nightmare of your former team mates?" Ahim asked. Ryunosuke nodded weakly and was about to cry until Ahim give him a hug to calm him down. "It's okay, I know your past cannot let go." she said. Ryunosuke know Ahim since they first met after the Gokaiger gave the keys back to the original owners.
In the living room, Sen-chan and Ban were playing video games while Jasmine is watching them from the distance. Those three Dekarangers left S.P.D since they went separate ways. They have know each other much before Ryunosuke and Ahim took their place as Super Sentai. Ryunosuke and Ahim later ener the living room to enjoy their relax until the alarm rang. "Akumaro..." Ryunosuke muttered. "Isn't he supposed to be dead?" Ban asked. Jasmine and Sen-chan angered at him for asking dumb question. "Sorry." he said. "Nevermind that, shouldn't we get going?" Jasmine asked. "Yes, we should. Titans, GO!" Ryunouske command as they went to find Akumaro.
Pretty much only the beginning. Sorry Shinkenger fans, I feel like Ryunosuke should get his own series and making the other Shinkengers died. Anyway, this chapter is the introduction on how the other Teen Titans formed. See ya!
