You know what I'm still confused with, why hasn't Takeru's Dad shown up as a manifested Ghost Parka yet? The Boost Eyecon is essentially Ryu Tenkuji so why hasn't he shown up yet to give guidance especially with the Ganmaizer running around.

You know what I would have done, split this episode into two, explain that Takeru is stuck in a limbo world since his Eyecon was broken prematurely and that it didn't fade naturally. Leave Boost out of the Eyecon's that got stolen or have it taken back. Have Ryu manifest as a physical ghost parka. Have him and Gramps inform them about Takeru's situation and come up with a plan to save him. Use that whole Necrom Gate+Outside Source to make a gateway to said limbo.

Next step, have Ryu and Gramps teach Akari how to make Eyecon's and have them make two. The first one be a stabilizer for Takeru by using his friends memories of him. The second one is so that he has a new place to put his spirit into. Cut to the next day and have Makoto stall the Ganmaizers while they get the gate working, then have Alain tag in and Makoto go with Akari to rescue Takeru. Plan is successful but as a side effect the stabilizer Eyecon transforms itself into Mugen, and then we get our little Mugen tease.

Admittedly this doesn't fix everything... but I think it would have made better context as a rescue mission than a, "Let's revive him through a miracle!" thing they were trying to do.
