I think would choose luffy from OP because he is very funny and cool, this is the top reasons
For me its Miho Azuki, her face is so refreshing..i really really like her. :p
Anyone from the Toradora crew haha, they are all awesome.
Minori and Taiga would be probably be best, Ryuuji though is a chill guy.
maybe kakashi of naruto or happy and lucy of fairy tail.
I would spend my day with Asuna from SAO. She is cool and pretty. Kirito would probably be with her too so then we could fight monsters or she could cook meals with her skills.
I'd wanna spend a day with Luffy of One Piece! Oh the adventure we'd have. XD
No where to go but up!
Makise Kurisu or Ino Yamanaka from Naruto
I wish the day won't end
Maybe with Rin Okumura
I would like to spend day with Tomoe from Kamisama Hajimemashita! ^^
I would like to spend that day with Moka Akashiya. Her sweetness is irresistable
