Look what I found /a/
I found the Takari proof! They really got married at the end of Dejimon Advencha 02. I was browsing through the net and I stumbled onto your website. It is mentioned there that Takaishi Takeru and Yagami Hikari didn't end up together, at first I was really upset and disappointed so I tried to watch the last episode of Dejimon Advencha 02 at www.youtube.com
and I was really furious now that Takaishi Takeru (or TK) didn't mention that he married Yagami Hikari. 2 days have passed and I was watching terebi (TV) in our apartment. here in Japan, Animax Japan already showed the Dejimon Advencha's last episode and next was the Dejimon Advencha 02's last episode. I said to myself that it's no use watching it because the ending wasn't that good (it's not good because Takaishi Takeru and Yagami Hikari didn't end up together). I was defeated by my liking of Dejimon so I ended up watching the whole show and boy I was surprised that it WAS MENTIONED there that Takaishi Takeru married Yagami Hikari. After BelialVamdemon was defeated, Takeru was typing onto his computer when his son came in and told him it was about time to go. Takeru says there that it has been 25 years and he married Hikari. I didn't believed it at first but when Takeru came to meet up with everyone, Yagami Taichi's son told his dad "otoosan mite mite, arewa Takeru ojisan!" (Look dad, it's UNCLE Takeru!) I was surprised by this because here in Japan we call our uncles a relatively way (it means that Taichi's son is Takeru's nephew. How did he became Takeru's nephew? He married Hikari that's why they are now brothers-in-law).
