Since Akutsu has nothing to say on the topic, he's not making a post about it or anything sappy like that.
The obvious present is a white motorcycle helmet, the kind with the visor to keep bugs/wind out of the rider's face. Left outside the door to Taki's room, it's not wrapped; there's just a bow stuck on it. Inside the helmet is a note, in Akutsu's handwriting, that reads "Let me know if it doesn't fit." (He tried to guess the right fit for Taki's head, so this helmet is smaller than his own, but...if it doesn't fit, then he'll kidnap Taki and exchange it for one that does. XD)
The not-so-obvious present is one Akutsu is trying to pretend didn't come from him. Therefore, it is carefully and precisely wrapped in silver paper with a white ribbon around the box and a white bow (looking about like
this, in different colors). Inside is a bottle of Taki's favorite wine. There's no note or tag, and this one is going to be found in Taki's school mailbox.
