In Episode 12, Ruri and Akito save Omoikane and stop it from attacking the UEF, and we see that Omoikane likes "Gekigangar" as well. It looks like a tree in the virtual landscape.
The phrase "重い鐘", which has the same pronunciation "Omoi-kane", means "Heavy bell". This meaning is also important in the anime series Nadesico.
You can see the Kanji descriptions and translations for omoi and kane (as used in kaneru.) I think this reading is a more accurate one.
