Akira was sleeping on the ground where he invented something

Akira: "zzz...I'm a genius...zzz."

Ravel: She sighs "Typical Akira." She smiles as she brings him to bed and snuggles with him

The next day

Ravel wakes up with Akira being on top of her which made her blush assuming that he wants to have sex with her as she started having perverted thoughts of the two having sex which she was even more embarrassed

Ravel: "A-Akira wake up."

Akira: "Zzz..."

Ravel: "WAKE UP!" Then she smacks him in the head which caused him to fall out of bed

Akira: "Oww!" Ravel pouts "What did I do?"

Ravel: "Y-you..." She still kept having those thoughts "Nothing! Anyways what were you doing last night?"

Akira: "Inventing something."

Ravel: "Does it involve with that weird gun you made?"

Akira: "Yep." Then he points the gun but it was pointed right near her face

Ravel: "Woah! Watch where you're pointing that thing!"

Akira: "Sorry." Then he grabs his two fullbottles as he shakes one of them, twist the cap, and inserts them onto the gun

Rabbit! Tank! Best match!

Then he opens the fore end of the gun

Are you ready!

Akira: "Henshin!" Then he press the trigger as his armor forms similar to diend's transformation 

Hagane no Moonsault! RabbitTank! Yeahhh! 

Ravel: "Wow. I did not know that'll work. And also why does it gives me reminder of Halloween?"

Akira: "We promise not to talk about 'it'."
