"I saw your future!"
When Sawada Tsunayoshi had the future diary, when my wife Yuno was deeply in love with Sawada Tsunayoshi...
"Tsuna~ I like it, I like it~ I like Tsuna the most!!!"
CP: My wife Yuno x Sawada Tsunayoshi
There is no Mirai Diary plot, there is no Diary War, it's just that Tsunayoshi has the Mirai Diary plug-in.
