This is what I think.

The flashback of the previous episode showed Gamou and Kengo's father on the moon and Kengo's father finding the Core Switch.

The preview for next weeks episode shows Kengo's father pushing the Core Switch, followed by a scene with a baby.

Obviously, the switch transformed in to a baby which grew up to be Kengo.

This is the timeline I think everything happened.

- Gamou and Kengo's father travel to the moon and find the Core Switch (as seen last episode)
- Kengo's father returns to Earth with Gamou, and then pushes the Core Switch, giving "birth" to Kengo (next week's preview)
- Kengo's father professes everything to Emoto (his fear of Gamou and the switches, what happened to the Core Switch, etc.) SPECULATION
- Kengo's father lies to Gamou about the Core Switch (senses Gamou's evil/power-hungry attitude), hence why Gamou has no idea where the Core Switch is (believes it to be lost as stated in a previous episode) SPECULATION
- The trio go to the moon and discover 1-8 of the Horoscope switches (Saggitarious, Virgo, Leo, Libra, Scorpio, Aries at least) and Gamou has Emoto betray Kengo's father (as seen in previous episode, switch retrieval speculation)
- Emoto, feeling guilty for what he did to his true friend and knowing the truth of the Core Switch, betrays Gamou (sensing and knowing his intentions) and creates the Gate Switch and Meteor Driver, as well as the MBUS (previous episode, stated by Emoto)
- Emoto creates the USB drive with all the information for Kengo

That's my best guess anyways.
